How the Sega Dreamcast Copy Protection Worked - And how it Failed | MVG
Вставка
- Опубліковано 20 січ 2019
- Did you know that the Sega Dreamcast had very sophisticated copy protection? I didn't either. But its true. The Dreamcast had excellent security measures in place. With the custom GD-ROM format that was not readable by any consumer PC CD and DVD drives at the time it seemed that the Dreamcast would be safe from haackers. That is until one fatal mistake caused the complete breakdown of the security measures.
And ultimately some say was part of the cause for the demise of the Sega Dreamcast.

Doesnt just develop a Karaoke GD-ROM

You know... it's just Japan and its unconditionnal love for Karaoke. That's the weakness.
I admire anyone who has the patience to transfer 1GB of data over a serial connection
Yeah like damn, that's dedication to "preservation"
@WolframaticAlpha Yeah, it is but as we know, USB technology is always improving in terms of data transfer speed.
@WolframaticAlpha Wow, thats very interesting, are there pics of it in google? i may try to find it.
Usb is not a serial or a bus. No fucking clue why it's called universal serial hus
But you only have to do it once
I will say, Sega NAILED the at home arcade experience with the Dreamcast. Hands down my favorite optical drive console from my childhood.
Very happy to hear that you will be covering copy protection. i've always been curious about how it works on different systems!
The best part about copy protection is the fun we all used to have defeating it! 😉
I'd like to know about this, especially considering emulation of disc based systems. You see, I'd just assume that the emulator of a disc based console would be able to read discs intended for the console it's emulating, but I do know that Dolphin (Gamecube and Wii) only works with ISOs and I'm not sure about other emnulators eg RPCS3 (PS3)
So I'm guessing that copy protection is something emulator authors have to get past not only on ISOs but also on the discs themselves.
LambdaCalculus379 I can bet any amount of money you had no part in any copy protection hacking 😂🖕
@@LambdaCalculus379 That saturn was a bitch....
Checking in one year later, he’s made some absolutely amazing videos on it!
Aah the memories of "Definitely not selling backups of the games on the school yard to pay for the console itself"
I used to do that but with PC games back in 1999 also. I got a Creative 2x CD burner for my birthday. First game I sold was a copy of Sim City 3000. The games were all rented for maximum profit. I had a library of games, software and audio cds. The kids would choose whatever they want and I would bring the copy on the next day. Teachers had absolutely no idea what that was all about. A full blown black market of pirated software LOL I had a really good pc back then I bought with all that dirty cash lol Good times!

Deoxal would have been really useful

Sega used one of the most effective copy protectios: by using a physical medium, that cannot be cheaply read and written.
And them, they included a version of a media, the could be cheaply read and written, and this become their fall.
well no because MIL-CD meant you could use regular CDs lmao. now the Saturn...the Saturn took _decades_ to crack the protection of
Damn its crazy people take time out of day to crack codes on video game consoles. How do they learn how to hack?
Utopia supposedly reverse-engineered Datel’s Action Replay CDX demo disc from DC-UK Magazine to figure out how Datel was able to boot their CD-based cheat disc. Datel had more R&D and could actually pay professionals to break protections. Heck, they owned their own media pressing plant too (Thin Ice Media), which is how they got around protection for the PSX. They went around Nintendo and paid Panasonic/Matsushita for the tech they needed to make bootable GameCube discs too.
That said, I suspect that the Utopia members responsible for the DC boot disc were probably Datel employees/contractors. ;)
Some good points here.
AfterBurnerTeirusu One would expect them to have access to the dev kit, or at least the software tools, since they had to do more coding. That was the easy part. There’s also a video from the about the hack resulting from a reverse engineered Action Replay CDX demo disc from one of Datel’s former partners (Larry Bundy Jr; 5 Hilariously Idiotic Gaming Screw Ups). Still, I’m interested in this other article.
The N64 devkit software was so prevalent at the time that they had to explicitly ban it from coding competitions like POM’99. The DC scene wasn‘t so different.
AfterBurnerTeirusu Yeah, it’s very possible that Datel paid a German group for an exploit they developed entirely on their own, but the AR CDX did predate Utopia Boot Disc. I recall a Datel rep on some of the scene’s IRC channels soliciting Game Boy coders for one of their projects (a programmable multicart that needed some legit content to justify its existence). They’ve definitely been known to reach out. ;)
What ever happened to the people that made the Playstation emulater called Bleem. Those guys reverse engineered the PlayStation so they could get their emulator running without breaking any copyright laws. Sony tried to sue the guys at Bleem but lost. Sony even went as far as to get someone to break into the Bleem office and try to recover sales figures on the emulator. Then came the Bleemcast to stick it to Sony. I wonder how it felt for Sony at the time, watching their games running and looking nicer on the competitions hardware.
@@BoomBox02 You might be mixing some of that up with Sony v. Connectix (Virtual Game Station) but, yeah, Sony sued both.
Connectix demonstrated VGS to Sony in an attempt to get them on-board but Sony didn't want any part of it. At that point they were using Sony's BIOS. Sony's refusal sent them back into development to make a functional BIOS substitute that didn't break any copyright laws. Of course, Sony still sued in an attempt to set a precedent and make all similar emulation illegal on the basis that it infringes on IP related to the rest of the platform's technical specifics. Luckily, Connectix wasn't such a small company (makers of VMWare) so they were able to defend themselves. When Sony sued Bleem! it was for "Unfair competition" and the use of screenshots to market it (deemed "Fair Use" by the courts). Imagine if Sony had partnered with Connectix instead and attacked the makers of Bleem! with that earlier lawsuit instead, which would have set a bad precedent for all of emulation. D:
You can actually read the "High Density" part of the GD disks in certain standard PC CD drives.
It involves burning a CD-R first, which contains the same type of TOC info that is typical for a Dreamcast disk.
You then load the CD-R, let the drive read the TOC, then do a disk swap.
Some CD-ROM drives have a wide enough tolerance for the spindle motor speed to allow the disk to spin slow enough, and the "HD" track to be dumped.
The trick sometimes involved setting the laser sled switch after the disk swap so that the laser will start reading the HD track first.
This can definitely be done, as I did it myself many years ago. The HD track really is just a standard ISO9660 track, just burned at a faster rate.
(and the GD drives have custom firmware to read the second TOC, and access the HD track.) ;)
Do you have the other SDK docs, with the "Sega Packet Interface" PDF?
There's also the System Architecture PDF, which I refer to as the "Dreamcast Programming Bible". Not that I'm very good at that side of it. lol
The closest I got to coding anything for the Dreamcast is when I did the first ever tests of an IDE HDD as a Slave device on the G1 bus (alongside the GD drive).
I modified the KOS examples to access the data on the HDD (or CF card), and print the sectors as hex.
I then designed a simple passive adapter, sent a few to Mr SWAT, who then added support for IDE devices in Dreamshell.
And so, the G1-ATA and IDE mods were born. ;)
You could disc swap to rip Xbox 360 games in img burn too. Or you needed a kreon drive
Did you even finish watching the video? He clearly stated in the video that you can read GD-ROM disc with certain model PC CD-ROM drives. You aren't sharing any new information here.
@@MrRobarino
That was using specific firmware which can allow specific drives to read the HD track without further modification.
The method I'm talking about is forcing a generic CD drive to read the track, by moving the laser sled zero-offset switch.
Two completely different methods, as the second way involves physically modifying the drive, and can work on many models, not just the ones stated in the vid.
(the wiki article shown in the vid may have contained more info on that method, but the link wasn't included in the vid description at the time of posting, so I couldn't easily check it.)
I loved the Dreamcast. I will never forget the day I was browsing the contents of the Quake 3 Arena game and found it was using an irc client for chat and edited the config to make it connect to my Quake 3 clan channel. fun times.
The good old days, when everything wasn't 100% gatekeeper'd by companies.
@@datriaxsondor590 That's the best part
@@JitSlayer true
I'm 19 turning 20 in March, I had a large spindle of CDs collecting dust, so I finally decided to buy a Dreamcast last spring due to the ease of copying. It's become one of my favorite consoles, and 1 Dreamcast grew to 5 Dreamcasts and MUCH more
I have 3 Dreamcast in public storage
@@Keepskatin My collection has REALLYYYY shot up since this post. I have almost the entire North American library of the REAL GD-Rom discs, I have limited edition dreamcasts and a demo kiosk console. WOW this comment takes me back to before I built it up
@@jk-474yoo that's so cool!!
@@KeepskatinI don't get it what do you use >1 Dreamcast for?
@@ThatPianoNoob Spare parts and backup hardware
Great video my dude!!! I forgot about how they circumvented the copy protection. It always amazes me that people discover ways to do these things! I gotta dig out my DC and fix the first controller port.
Funny that burned GD-ROM discs still can't be self booted. Of course finding blank GD-ROM discs and setting up a burner really isn't worth the time, but even now if you ever get a hold of a burned GD-ROM the only way to boot it up is using the System Disc 2. The System Disc 2 wasn't reversed either, so you have to track down a legitimate copy of that as well!
You can swap a retail gd-rom for a burned gd-rom or a gdr and if you get the timing right it will boot
@@MrXiandra Gotta Love Them Hot-Swaps!
I had self booting back ups later on in the dreamcasts life about a year after the boot disc appeared
@@carlopepi sorry for confusion, the above is referencing gd-roms not CD-Rs
you couldn't buy gdroms.. they did that for that reason alone. no one had a gdrom burner..
GD ROMs weren't a viable option anyway but CD's were.. hence why that was the ultimate choice overall..
if people could buy gdroms and a burner.. probably would have been the price of a house.
Piracy as a factor for the Dreamcast's demise is seen by some to be rather debatable as it could be argued that the PlayStation was plagued with pirate and bootleg releases yet that didn't kill the platform.
Annie Warbucks it was sega making way for Microsoft I believe. Sega was running out of money at the time where Microsoft was not.
@Lassi Kinnunen Not to mention that Sega's previous business decisions undermined consumer confidence and made gamers leery about the company. Sony's announcement of the PS2 with its DVD playback capabilities was the final nail in the coffin.
@@BADSeCt0R2XP Sega bungled up with the Genesis addons and the Saturn. The 32X was kind of pointless as most of its games were merely slight facelifts of existing titles even though the hardware does have potential. The Saturn had a lot of flaws both on part of the hardware and how it was marketed. It was infamously rushed to counter the PS1 in the States, and its hardware was and still is a *nightmare* to develop for. That certainly accounted for why they were in dire straits at the time.
The UK TV advert i saw was obscure as not to explain it was a console advert
Not to mention the Wii which was extremely Easy to mod, no chip required and allow it to play downloaded games and rip a game to ROM and be able to then play it from the ROM making it easy to copy games you would rent.
Something you didn't mention - when I first bought my Dreamcast, I was told of the battery removal trick. If you remove the internal battery for the Dreamcast, as well as tie back the clip that detected the GD-Drive door opening, it allowed you to play multi-region or backup games. You would insert a legitimate disk, and the Dreamcast would read the files it needed to boot whilst at the same time asking for the current date/time. You then wait about 2 minutes for the disk drive to timeout and stop spinning the disk. Then you could open the drive door, change the disk to a different one, and then select continue on the data/time menu. Worked really well but I remember you needed to boot different original games depending on the backup you wanted to boot...which makes sense now that you've explained the ip.bin file containing data for the game :)
Dreamcast copy protection, was about as effective as using a twist tie to Lock your bicycle up in the middle of Brooklyn!
They left the bike lock at home
Aaron Greenfield Dreamcast copy protection was fine. If someone gives you the keys to unlock something is not necessarily the locker at fault.
@@BADSeCt0R2XPDreamcast fanboys are the most closed minded of all system fanboys.
the GDs were safe, for many years no one was able to crack them, but the mild-cd support killed the dreamcast, who the fuck thought of that?
@@BADSeCt0R2XP Fine? The scrambling was a good idea, but as MVG mentioned Sega screwed up by having it be the same every single time.
Easily reversible encryption is about as useless as no encryption at all. It isn't a matter of "giving you the keys", they chose to use a flimsy Master lock that can be easily defeated once you see what is going on.
I wouldn't mind seeing an entire series on this. Not just on how copy protection works and how it was defeated, but on how developers would detect things like mod chips and modify their games if one was installed.
One day, about 17 years ago, my Dreamcast stopped working. It started out first as the discs not playing games properly. Then, it just finally died. No power. Plugged in, power -- nothing. It shorted itself out.
The fix is a new disc drive, which I've yet to acquire. But I still have my Dreamcast, which I believe is a first revision...I will never part ways with it!
I remember finding out about 12 years ago that Dreamcast could play backup discs with no mods, i went to the market and bought one immediately to see what i'd missed out on. Disc juggler to burn the games, good times
dude... when you put that verbatim disc in the dreamcast i lost it. im literally sitting here with my dreamcast and a stack of verbatim discs that i've been burning homebrew on
I've been waiting for you to do a video on this! I've tried my hand at making some repros for the Dreamcast, and it's Soo cool seeing these games preserved on physical format!
I have to admit I went into this thinking it had zero copy protection! The speed in which I saw copies available was incredible back then.
“This disk for use only on secs Dreamcast” my favorite album, listen to it daily. It’s really good, that voiceover... perfection
Hey, been watching your videos here and there for a while now. They're really great, I appreciate your enthusiasm and the production is good and your voice is nice to listen to. Thanks for making them!
That "Warning..." message when you put a Dreamcast disc in a CD player was SUCH a hit of nostalgia!!!
"How did the Dreamcast Copy Protection worked?" "It didn't"
I also had always heard that the Dreamcast simply had no copy protection, and that always sounded odd to me, but I never knew enough about what was going on behind the scenes to be able to do anything other than take the claim at face value. Thank you for making this video to add some clarity to what had been bugging me for these many years.
By the way, did someone manage to break the security for that version 2 of the Dreamcast?
I remember when I was looking to buy one I had to find a specific version or else most burned copies of the game wouldn't work on it. When I found mine though, it actually didn't have ANY such number printed on its sticker. Turns out I got a demo kiosk unit instead of a regular commercial unit. I really want to know the story of how it got to me, but sadly the person I bought it from doesn't know where it came from originally.
Really enjoying these copy protection videos you're doing. They make me want to get one of each of the consoles and mod /exploit them for the sake of it.
Great work!
Awesome video, can’t wait for the follow up, Xbox and DC scene is also very close to my heart, Kalisto with the first self-bootable rips, Echelon taking over, using DiscJuggler to burn, those were the days, I remember making a ripkit for The Warriors on Xbox that would automatically resize the game for you to fit depending on if you wanted, SD video or HD standard or widescreen, oh those were the days, keep up the good work MVG and I can’t wait for the next video

Always love when I see a new MVG video on my sub feed, great stuff dude! Very informative.
Great video mate, you're killing it!!
v2 can read CDR. Only the US region got the v2.1 BIOS that removed Mil-CD. All PAL and JP region systems could boot CDR copies. We dumped the Non Mil-CD capable systems BIOS which just had a modified Kabuto. only JP made NTSC-U Dreamcast made after October 2000 were subjectable to this. Chinese made systems didn't have this and only way to know for sure was to dump the bios in parallel or simply look on the DC main board to see the 2.1 revision. My main DC was a v2 system that loads CDR just fine. The info you have is a common misconception but my time in the early days of the DC and work with Trurip, TOSEC as well as the DCCM and ReviceDC projects have debunked this a long time ago.
Well let me guess, this is my old pal Atreyu187? So we meet again!
BFKAnthony817 that would be me hehe hey Anthony817
Hah I knew it! Nothing much man, same old same old. Where have you been not seen you in the DC community much, and only once on that PS3 subreddit.
BFKAnthony817 NM I don't have any systems ATM due to some stuff so I just lurk and help.
Ah man I hope you can get your collection back. I just got a GDEMU and 128gb SD card for it for my Dreamcast, and am building a DreamPi so I can take it online over modern internet. Really back on a Dreamcast kick like never before.
I absolutely love these video's. I don't have any game consoles, only had the Master System when I was very young. I never play games on a console, I'm not much of a gamer even. But I trully love your videos about it. It's great to hear someone with the amount of knowledge you have talking about these things. While keeping it all comprehensive for everyone too. Great work.
I can only dream of making such good video's. I review SBC's. But I've got sooo much more to learn, and even if I can learn it, it will never have your standards. Thank you for all the great content, greetings. NicoD
This was a really, really cool video. I’m fascinated by this type of stuff. Thank you so much for putting this out! Can’t wait to watch the others...I feel a. Assume binge coming on!! ;)
Yeah u should do a copy protection series.
What you don't hear is the firmware on the gd rom drive originally contained the master key for games and earlier games where easy to bypass its model 2 and three revisions that stopped piracy quick
You definitely deserve that 100k UA-cam plaque. I always enjoy your content because every video is so unique and interesting! Keep it up 👍😄
Fantastic video as always. Even when I am familiar with the topic you always manage to teach me something new or offer a new perspective. Thanks!
Basically you wanna look for the Sega enterprises label when they dropped support for mil CD they changed it to Sega corporation I believe. Ive had a number two Dreamcast be able to play back ups and one with a number two that couldn't. If your dream cast is made before November 2000 with a number two I believe that you can play back ups hope this helped . There's an interesting article where I read all of this I'll try to link it tomorrow sometime. Love your videos man!!!! Keep it up!!
Thanks for posting this. I was always intrigued by the GD copy protection back in the day and reading the release notes from groups. This is kind of random, but there was a note by Echelon on the release of Razor Freestyle Scooter that says: "Protection on this game was a bitch, especially considering it is only
$19.99."
I copied that out of the original .nfo, but I'm curious if you know what (if any) software tricks developers used as an additional attempt at copy protection? I remember also reading about dummy tracks, but the explanations as to how exactly they worked were vague. Perhaps you could add some info on GD software protection in an upcoming video. Just throwing it out there - anyways, keep up the good work :)
I love your videos about copy protection! One thing that I’d like to suggest is that you make a video ranking in your opinion what are the 10 hardest to defeat console copy protection schemes.
good suggestion! i may look into that for a future vid. thanks :)
really enjoyed this - please continue making technical vids like this
I always thought that the Dreamcast's copy protection was bad. This video showed me otherwise.
i personally thought it was non-existant, now I know for a fact it was bad.
"It's funny because one of the main cause of Dreamcast's copy protection breach was because some Action Replay demo disc"
YES this is what i heard , i bought the magazine that the Action Replay came on , it allowed any backups to boot , as i heard the Action Replay demo ( free disc ) with mag had the boot codes on it unprotected
Stoked to hear there going to be more copy protection videos! Something about the early PSP days would be awesome! Stoked to hear some word of mouth original Xbox stuff as well! Great work, and great channel!
Love that MP2 theme, i'm happy that you use quality themes from great games for you videos
1:32 - 2nd Console?
1 - Mega CD (Sega CD in US)
2 - Saturn
3 - Dreamcast
The Sega CD was a peripheral, not a console.
AztecCroc fair enough, however one could just say the Sega Genesis is a game console that had a peripheral allowing it to play disk based games. That would still make it sega's first.
@@AztecCroc How's about Sega Wondermega, then? The HWM-5010 from Sega, not the Victor's variants. And the MultiMega/CDX ones?
It's an add on
Wondermega isn't addon, MultiMega isn't addon, either.
I never really got to do much with the DC, but this was still to learn about nonetheless.
Always enjoy your videos! Very informative as always. I've considered buying a Dreamcast just to rip the games to use with emulators, but does that SD Card method work for dumping the BIOS as well?
Great video. Always like to hear stuff about copy protections, it's been a fascination of mine since the early 80s. :)
When I read this title I said to myself, "What copy protection?" lol back in the day i remember dreamcast games being easier to copy and play than ps1 games and those were easy as well
Wow, I didn't know about ripping GD-ROM discs. Yay, once I get a GDEMU console, imma get all those fully ripped dreamcast images!
I love this kind of videos!! I wish more could explain like you have, for example what dr. Abrasive did to unlock the saturn i didnt understand any of what he said. Billions of thanks, intresting and enriching! Although im not very good with english, i greatly like your educational videos! Thanks mr.

when the dreamcast supports mice but the iPad Pro doesn't
ARS DC was so far ahead of its time, especially in Japan where the mouse, broadband adapter, I believe a camera, and (if it was made, a vmu MP3 player. So D.C. Had nearly all widely used PC components (except internal storage). Keyboard, mouse, live audio chat, modem/broadband, web browser and (I've heard rumor of a basic but very functional "Office-type" word processor & spreadsheets), live video chat, web camera. I'm betting some found ways to use the expansion ports on the back to connect printers, and the ILLUSTRIOUS VGA box/cable to play 480p so sharp on a pic monitor. Dreamcast, aside from storage limits had most bells and whistles of a $3,500 pc at the time for $200. Buying all the options adds up some, but not late 90's/early 2k's absurd prices. also had online multi-player. And my favorite: lots of killer games and arcade ports you could play by just pressing "power"- no crazy conflicts and patches and incompatibility that was so sloppy on pc- like physical jumpers, that made me spend days trying to get one crappy pc RPG to work with hours of tech support. Screw that noise: inert disc, press power, and it worked.
@@sideswipe1261 The VGA box was amazing! I had a Gateway VX1120 CRT monitor that was a huge (back then) 22". Shenmue and Shenmue 2 looked absolutely amazing on it.

Extremely pleased that you’re covering copy protection! - I really can’t wait for the next episode! - However, this new series might be a double edged sword. I bet tons of big name hardware developers watch your content like a hawk and will be creating notes to avoid mistakes they’ve made in the past.
They do not need UA-cam channels like this to monitor security. They will be on hacking groups and release groups forums instead.
Fantastic video MVG! I just recently got a Dreamcast for Christmas and I’ve been playing it more then my current gen consoles. The library is just that clean!

Modern Vintage Gamer, Dreamcast, thumbs up!
Great video, not a lot of people would know this stuff, if they where not in the scene. :) I remember buying Chiller by Mastertronic for the Commodore 64, I tried to make a backup for a friend of mine and the backup wouldn't load, I used a sector editing program and figured out that on the 5 1/4" diskette there was a sector error that caused the head of the drive to jump to another sector and continue to load the game. So all I had to do was make a duplicate of the game and then recreate the sector error on the backup version and voila it loaded just fine, and no internet back then to lookup this stuff :)
You explain this so well I had to include a link to this in my video about the Australian launch of the Drerramcast.
"...If you 'BOUGTH' this CD you have been Cheated..." I love how EVERYONE missed the Typo
My dreamcast plays burnt discs without a boot disc
This is because Echelons method of booting was released and most DC game downloads today used a prepared ISO with the exploit already in place.
Nice vid!
ps: there's no one better than you mr. MVG to bring us a series of "games locked on a single platform" and how to play 'em in 2019. CXBX emulation, x360, ps3 and wiiu are getting better and better. Would be kickass to see how these perform (properly played, controllers and all) versus original hardware. You're the man up to this task, mvg!

Truly fascinating info, and very well put together!
1:28 If you really know your SEGA consoles you'll know the Dreamcast was actually the 3rd SEGA console to use an optical drive...
technically the 4rth if you count the portable sega cdx
@@swfreeD why would cdx and sega cd be counted as 2 distinct consoles?
If a dev kit has a memory viewer, deciphering a scrambler is only a few RAM dumps away.
To be fair, it was much more sophisticated than the BCA of the Saturn discs...
But took a lot longer to get a mod that worked around the "fortress" of a cd drive controller. My favourite is the mega cd which has no copy protection at all.
Saturn was better. Sophia ran Checksums and Lockjacking. Dreamcast used GD-ROM. GD ROM is basically HC CD ROM with all TOC packed on one layer. Dreamcast Copy Protection was all Software in the Whitebook of GDROM itself.
Great new Logo MVG!
Good stuff MVG. I'm going to need to pick up one of those serial to sd dumpers! Even with a gdemu it would be nice to have that!
So basically these where the original r4 cards?
Love the Dreamcast!
Excellent coverage. One thing I'd like to add is that some games had more than 700MB of data on the GDROM (video files mostly) and those couldn't be copied over straight; we had to RE the video format and come up with tools that could transcode the movie and audio files into smaller sizes. In extreme cases, 22KHz ADPCM stereo audio would be turned into mono. The quality suffered, but it worked. The only two games that were too big *and* had no movies/audio to transcode were D-2 and Skies of Arcadia (all cinematics were in-game, and the audio was mostly speech which was already 11KHz mono IIRC). In both cases, the data had to be split onto two CDROMs and instructions were given on when/where to swap discs. Kudos to the developers of those games!
I used to rip games for ReviveDC. D2 is a very curious one that we looked at a lot. The ADX decoder in that game is actually tied to the sample rate of the audio files in the game. Trying to reduce the size of the audio files results in scrambled audio. It's very bizarre and it's the only game (to my knowledge) that had a decoder that was hardcoded to the sample rate.
@@ComradeJared Nice, what was your handle back then?

CDROM Sonic Adventure also had mono and resampled audio. And the music from Sky Deck part 2 was dropped too, i got to hear that song looong after, when owning an original copy haha
Fun fact. I was good buddies with some guys at a Japanese game company that were doing a relatively high-profile DC release back in 99 (2000?). The Utopia disc had just hit and piracy was blowing up, and they were freaking out. We came to the conclusion that the only way to keep the game from getting ripped 0-day was to interleave the game data on the disc with junk data and artificially inflate its size to the max capacity of the GD-ROM, and the lead coder said he'd try it. I THINK this worked, because the main DC warez group had "refused" to release it on day one, saying "You guys don't deserve it because you take us for granted" or something along those lines. (Of course, they wound up getting around it a week or two later, as expected.)
BTW about Dreamcast anyone know where I can find Dreamcast Homebrew community ? There many result in Google but I don't know which one still active.
So jealous of your Saturn.
My understanding was the key to this process being discovered when Gameshark(or other similar software) sent out a demo disk in a magazine. It allowed you to boot and play burn disks. This was the first crack in the armor.
Awesome video! A lot of little details i've never seen before.
2:32 Sounds like she's flirting with the player.
I can just see the player responding: "Will you sleep with me if I play it on a Dreamcast?"
Dreamcast version 2 is still unhackable to this day and most likely forever.
I can't wait to hear more about copy protection! Please do more!!! LOVE THIS!
Really looking for the next video. Really interesting stuff!
9:19 Not necessarily 100%, as I have a revision 2, which boots backups.
Ironically, I have a rev 0, and a rev 2 Dreamcast, and not a rev 1, meaning I can't use gdrom emulators atm, unfortunately.
Nice vid as usual though. Was a nice watch.
How do you tell the revision of DC?
@@sabata414 If you have a NTSC:U/C or PAL console, then look for a number in a circle on the label - that's the revision. If you have a NTSC:J console, you have to take it apart.
@@TrimeshSZ thanks
:D
This is very interesting. I'd love to see more about copy protection. You rock : )
Very interesting. I look forward to future videos covering this topic.
