I have waited 20 years to finally see the inside of this thing after first seeing it in 2003 online.
I don't think I've ever seen one of these taken apart before.
@@Crux161 A feature the stock dreamcast did, had a built in 56k modem that could be swapped for a broadband or LAN adapter (I have no idea what the difference between the two latter are, since both are Ethernet).
@@_MasterLink_ they're probably just different names for the BBA
@@avegee24tv I had to look it up, they are different. Broadband adapter is 10/100, LAN adapter was 10Mbps only. LAN adapter only works with one title and is Japanese only and runs on a Fujitsu chipset, whereas the Broadband adapter runs on a Realtek.
@@_MasterLink_ You serious? With the modem you dial a number, with Ethernet you join the local network...
It's kinda wild to think how I used to use one of these as a footrest after we stopped developing Dreamcast games.
They were the perfect size for foot rests
@@the_mancavewithjacobon the side or standing up, based on foot height preference
I’m using an Osborne 1 computer from 1984 as a footrest right now and this post is very relatable
Doing God's work.
Yeah, that never happened.
GD-ROMs can be read with a few Plextor IDE CD burners and a patched firmware. You can't create them without GD-Rs, of course, but at least clone them for archiving and emulation. The common way is to use a program on the Dreamcast that slowly transmits the disc image via serial connection to the PC.
The software side of the Katana is pretty much obsolete today as there are better Open Source development tools and libraries available, unless one really wants to utilize WindowsCE for any reason.
The machine itself is just one of the most beautiful console devkits ever. Thanks for taking it apart :)
I have a plextor drive on the way to do this as the redump tools spin the drive down which means I can load a good TOC and then read the high density region, so thats my best bet I think.
Man this brings back so many memories of spending so much time in CodeWarrior writing homebrew for the dreamcast. It was a really fun console to homebrew for what with how easy it was to make bootable disks.
What kind of stuff did you make?
@@SonicBoone56 Yh I'd like to know :P
This is why i generally use dd to image any drive, cd, or dvd for archival purposes. Having a full backup to look into all this will be wicked! This thing looks genuinely so friggen cool, thanks a million for showing this off. It's really a dream!
Yes, dd would deffo have been better
What is "DD"? I know about Macrium and Acronis but not that
@@mitlanderson Data destroyer lol. It's a command that comes from UNIX.
@@RossComputerGuyData duplicator feels more apt nowadays
@@TylerFurrison That's it's other name. It's called data destroyer if you're destroying data or messed something up.
Havent seen this dev kit since 2000’s bring back so many memories
Having to burn off and send gold masters discs of to Sega was a pain the the ass,
@@johnwells558same with Sony (was it 9 copies?) 😉
@@frioglobal yes matey, it was a pain when the project was finished, had to archive the entire code, graphics and drawings. CD drives wasn’t that fastest back then.
Been after a Dreamcast Dev Kit for years, Found a Sega Saturn one last by total chance, the one NBA JAM TE was developed on, but Dreamcast ones never seem to turn up. At least for a decent price.
I never really stopped to think that a dev kit would need to be tethered to another computer to function. They have been all in one units in my head
nope. its industry standard for devkits lol, i mean how else are you gonna make sense of all the data that's produced from the cpu executing binaries compiled for it.
not only that for rapid prototyping, youre gonna have to have a way to load newly compiled games without manually flashing them onto re-writable flash carts or worse burning a new cd-r every time! (imagine how much would a dev studio be spending in cd-r's if they had to do that!)
its probably not the case for more modern consoles like the xbox series x or ps5 since they can just connect via ethernet and do everything that way.
Out of the dev kits ive owned here are how they worked with or without a pc:
The Nintendo NDEV (wii dev kit) needs a pc to even start and loads everything over usb very similar to the dreamcast to a degre.
The Nintendo IS-NITRO-EMULATOR does not need a computer to boot and can play GBA games in this mode. To play DS games a computer is required to load a rom file but also needs a ds cart for saves only, this can be a dev cart or a retail cart with a compatible eeprom for the rom
The Sony PSP Dev kit does not need a pc to do anything other than debug stuff. you can boot and use the menu as usual and even toss in a retail psp game in the UMD drive. The CD/DVD drive can also be used just fine as long as its a master disc.
The SONY PS Vita dev kit does not need a pc to boot or to play games but does need a pc for debug stuff. Retail games could be played.
I also had a test kit for ps3 and ps4, both could boot and run but the ps4 could do basically nothing unless it had proper game files for test kits.
EDIT: Sony stuff used ethernet or usb for stuff depending on what was happening. PS4 could do menu things and such i just mean "nothing" for playing games unless they were the right package or disc type.
Learned something new
@@generic6099It could be done since the 8-bit consoles.
I love to see this DevKits, the way it's build says a lot about how hard it is to make a console.
Seeing you tinker with the hardware and software, instantly takes me back to that wonderful time of computing in 1999. Like finding the rights cables in a box or just experimenting in Windows to see what would happen. It still bugs me that Sega didn't outlived the home console market. The Dreamcast remains as one glorious piece of gear.
Wow, great showcase of this unit! What a cool looking thing.
I'm sure you've heard this like a thousand times already but the gdemu 4 gig limitation would be a perfect use case for a bluescsi so you could have a bunch of 4 gig drives to work with
Had no idea these boot retail GD roms.
Me neither!
I believe that's how the first games were dumped. Somehow pirates got Katana devkits and would use it to dump roms.
@@BurritoKingdom Would be cool, but too much of a stretch IMO
@@RadikAlice nope. It's a true story. The homebrew group utopia got a Katana dev kit back in 2000.
@@BurritoKingdom Well that explains why they were among the first, if not outright the first to crack a game for the console! Cool!
Take a shot every time he says scuzzy.
Dont do this, you’ll end up with alcohol poisoning and I cant in good conscience recommend that!
Subscribed in the first 60 seconds just on the production quality.
WOW that was amazing, i cant believe it uses an emulator instead of real hardware, and that boot animation is cool, thanks for that keep up the good work.
SCSI drives always sound like a tractor starting up, warms my heart :p
This amazing, have been waiting for Katana DevKit tear down :)
27:18 Seen this intro everywhere but never seen a unit actually properly boot up on camera, really good
Still have my original Dreamcast. So under-rated. Ahead of its time and needed decent internet.
By the way. despite the fact that it seems you can simply replace old power supply with modern ones, this may not be a trivial task. Modern power supplies are designed for a mandatory 12-volt load, unlike old ones, so without it you can easily get problems with stable voltage on a 5-volt rail
The hard drive and other components still use 12v which sure will be less than a modern PC but its still enough for most modern supplies to regulate properly
Great video ! I had a katana devkit and i got it working on a windows xp sp3.
С1\С2 - Возможно : "Console 1/Console 2". Порт параллельного сопряжения двух консолей. При этом, текущая консоль может выступать как ведомой (С2) так и ведущей (С1)
Gotta love the sound of a older computer/HDD spooling up during startup. Somewhere I got a old IBM 386 SX system with a big orange juice carton sized HDD… took damn near half a min to spool up. Sounded like a turbine engine.
There’s one on eBay someone selling for $5.5k (4.5k bid now), supposedly in working order and containing a prototype of the grinch. May be fake, but might be worth preserving too. Much as I want a dev kit to mess with one day.
Literally how do you not have a million subscribers yet
Make sure to share it around so we can achieve that!
Awesome video and very well explained :) .
27:20 woah did not expect that. that IS the devkit startup. ONLY FOR THE DEVKIT!
This thing is built like a PowerPC Mac pro , nice
One time i literally just taped a cracked cd back together and it worked, it's a long shot but it might be worth it.
Wow! Awesome teardown of this little gem. One thought about the GD-ROM drive: you mentioned that it is not ATA (or perhaps ATAPI) compliant. It might be possible to get it to work with a really OLD IDE controller (from the 386/486 days) that does not support ATA commands at all. Something by Winbond, Promise, or Data Technology come to mind. Mind you, though, that they would have to be ISA or VLB. Just a thought...😁
It will certainly not be speaking IDE as that was only used for hard drives, all other PATA drives use ATAPI to tunnel SCSI commands as SCSI supports media like CD drives. But it’s probably deliberately made to not work with conventional IDE controllers so bootleggers couldn’t easily rip and replicate discs.
Amazing video
29:13 - Shut your mouth boy; Thems fightin words. Hahahahahahaha!
Trust me I like Gauntlet Legends/DL, I used to own the original arcade PCB ;)
I can't believe that sega used mosquito repelling coil as their logo!😂
Lol 🌀
Maybe thats a Spiral Magic symbol since its name is Dream Cast as in "cast a spell" on you, to make you dream. 🌟 😅
nice vid and nice channel, you got a new subscriber
This was both fascinating and frustrating at the same level! Great content, though!
The good news however is the game files are confirmed to work and its a very early version!
@@NaokisRC what a shame there's a crack on that "GD-R". You did an amazing job!
I just saw your post about someone managing to boot the beta on an emulator! So cool!
fond memories of my Dreamcast. 'The body may die but the soul lives on in SOUL CALIBUR'
46:30 ah yes, the best video game of all time
The Katana BIOS boot screen music reminds me of Japan train station jiggles. It’s cute.
"I love plop."
I dunno why, but that made me laugh
Very neat. Hope your friend gets some good use out of it. Trying to find one that isn't overpriced is next-to-impossible these days.
I'll give the archive a try later. It looks like it's encountering an exception and causing the Debug Adapter to set a breakpoint. If you hit F9 it should retry and tell you what the exception is. My guess is that it could be a missing sound driver.
It just skips to an illegal opcode when i tried
Bad news, I'm afraid. There are quite a few files missing. Though, if you move all the WDL files under the DATA directory at the root of the last MODE1 track, you should at least get it running under the Time Trial mode. Anything with AI characters seems to cause a read error in memory (looks to be a bad or uninitialised pointer). There's a performance graph on the right-hand side that doesn't appear in the PtoPOnline video and seems to be the main difference (except for the missing character models).
Very cool video, that's a subscribe!
Maybe you can talk to the folks who worked on the recent dreamcast games, or work with MVG to get things sorted out
Three members of the DC community have gotten in touch and I am actively working with them to get the contents all archived 🙂
Sounds like a good use for a blue scsi emulator to replace the drive
Absolutely fascinating video Naoki, thanks for putting this comprehensive look at the Katana together and putting it out there! I was a huge Dreamcast fan back in the day and it's fascinating to have a poke around the actual dev kit with you. Agreed on Sonic Adventure as well - I barely played 2 but I certainly enjoyed the first one despite what the haters say 😁
Ahhh the sweet sweet sounds of yesteryear.
Really cool
pure gold here...
love your video mate dropped you a sub also i noticed you used the same music that dankpods uses to test headpoines lol with on his channel that same jingle tune lol ! had me laughing
Wow, the dev unit is almost as loud as the Dreamcast’s original fan. Almost. 😂
That's one clean computer. It looks like it was either cleaned up or barely used.
If you mean the compaq, it was cleaned up by myself. If you mean the katana then yes I think it was not used all that much!
11:35 USB-to-SCSI adapters are stupid expensive.
Indeed. But I felt a need to clarify in case people suggested it
The Sega Dreamcast was the best smelling console back in 2000.
the reason the dc controller had the cord on the opposite end, in cause people played with the controller in their lap, the corn coming from the top would pull it away from you when you didn the gamepad pull when jumping left or right, but when it comes out the bottom it pulled more into you hands.
awesome video !!!,Dreamcast is one of my favorite retro consoles in my collection, i still having fun with it. i just wonder if its possible to connect a GDmenu board in that development unit....it would be great to see if it works.
멋지네요!
Bro, that music! For most of the video, I thought your voice was the background music. However, good video
helping cast dreams!
I expected jankyness inside, but boy was I wrong. It's pretty sweet.
If you have “coders cable” (serial) you can dump out the GD-ROM (slowly), or using the broadband adaptor.
The disc wont read due to the crack. I am getting someone more professional to look into it
I have that same Compaq Deskpro EN right beside me!
Ohhh... The Dankpods Test Audio :) @10:40
For reference to the IDE drive chip, IDE CD drives actually use SCSI (yes, really, it's even possible for most OSes that support both SCSI and IDE CD drives to support obscure SCSI hardware that was _never_ available for IDE via an IDE SCSI converters... there's at least one soundcard, for example) transported over IDE, so all that's really needed is a _relatively_ cheap repackaging of commands.
Yes ATAPI is tunnelling SCSI over ATA Packets (hence the name ATA Packet Interface), but my comment was that the GD-ROM drive was an IDE/ATAPI standard when most consoles prior and of the time (excluding the OG Xbox) used custom and proprietary interfaces. That and the fact the fact could tie it to the GD-ROM system for the Naomi.
You need to have that cute dragon logo animated^^
Absolutely something I want to do, but have a lack of skill!
I love plop it's a great little utility except it doesn't work with one of my computers. A ThinkPad 770 which has the distinction of being one of the few devices shipped with a USB 1.0 controller which I think is why plop won't boot a USB drive on it. Also had the distinction of being the first laptop available with a DVD drive, USB and support for AC-3 audio. Fun computer over all.
Anyways loved this video on the Dreamcast dev kit it's my all time favourite console and cool to see the device so many games were developed with.
Thanks!
Thank you so much for your support!
plop needs 46MB of ram! it's so hungry!
I have a Dreamcast katana and it would only show up as a drive...i finally found enough terminators myself...hoping the thing works. I have a dolphin DDH gamecube kit that worked until it didnt. and as rare as they are, i can't try and fix it
Send it to someone on UA-cam who repairs game consoles
@@Keepskatin nah. It costs far too much to risk shipping and there’s not a ton in it to fix. It’s not a normal GameCube so part swapping won’t work and it’s a lot of fpga stuff. I hope one day to try with a known good IPL rom but until then it just rots.
Seeing a yellowed Dreamcast is so wild. Idk how common it is for them to do that, or which region has more of them, but i always end up seeing yellowed consoles on UA-cam. Just a curiosity, not a jab.
This is the second time it’s yellowed. I retrobrighted it back in 2018. But what’s strange is that it’s even yellowed on the inside of the plastic, not just the outside like they usually do.
It’d be sooooo cool if someone started modding these with some premium soldering. I bet we could find a way to make this super speed
9:55 PREACH!! 😂😂
i'm curious why you didn't install the visual studio, there could be certain integrations between the programs that require an instal of vs to work.
Possibly but it wasnt the scope of the video and would require coding to show off breakpoints etc
Besides the crack, I think you need the "System Disc 2" boot disc to load GD-Rs. If the drive can read through the crack, that might be the reason it's claiming it's not a game disc.
what about a SCSILVD to SATA adaptor that would let you use your hard drive in a modern PC.
I didn’t have one to hand and didn’t want to order that in. I had the stuff you see in the video already at the time of recording.
it wasn't the best console of it's time but it still wasn't half bad. i actually loved it tbh.
Send the disc to Louiss Rossman!! I believe he has the tools to recover!
I wonder if one were to make a middle man board for the gd rom drive to provide responses to commands like AT drive info, if one could make it work with a PC… I’ve seen crazier adapters made of an RP2040.
It’s not impossible, i just don’t think anyone has tried.
Now I’m tempted. When I got more time and money, I may need to buy a dev kit and/or GD rom drive to try this out with.
You could probably do it just with software - the GD-ROM electrical interface is PATA with a few additions (33.8868MHz clock output, a pre-emphasis enable line for CDDA and a serial transport stream that's basically I2S except the it has LRCLK lined up with first bit of each word rather than one bit cell earlier like Philipps I2S) - the software interface is sort of like ATAPI, but incompatible. Annoyingly, Sega called it "SPI" (for "Sega Packet Interface"), so searching for information on it tends to generate a lot of hits for the other better known "SPI" interface). Try searching for "cdif131e.pdf" - that should turn up the official Sega documentation for the command set.
I always wonder what would have happened with the dream cast if they used dvds instead of cds.
Probably not a lot. Sega already had enough troubles with cash, getting a DVD license would put costs up, Sony would also have tried to stall production of the Dreamcast and even then the hardware in the DC was just not competitive with the rest of 6th gen consoles as GPU tech was accelerating fast. Sonic adventure 2 battle uses twice the amount of polygons for Sonic’s model on the GameCube compared to the Dreamcast, for example.
Technically not cds, but a halfway in terms of tech, they packed more than 750mb on the disc, and only the first bit of the disk counts as basically a mini cd, with the rest being GD and unreadable by most regular cd drives, without firmware hacks iirc it’s not possible even with compatible drives, but it’s been awhile. All I know is when you burn larger games to cd, you often sacrifice FMVs or music (quality lowered or removed/replaced by the smallest file. Sonic Adventure with every track being Station Square I remember VERY clearly……)
gots to find a way to get that dreamcast shell a tad more gray and less yellow?
I already retrobrighted it once before
could someone use one of these dev kits to re-port Sega Rally 2 without the slowdown caused by using the windows ce api?
that would be one of my top 5 dreamcast fan projects
Sure, but you either need to rewrite the entire source code or had the original and modified it. But time spent vs end product is probably why it hasn’t happened
Cool
Is possible to run windows ce desktop?
And some of windows ce software(not made for Dreamcast, made for other ce devices)
AFAIK there is no CE desktop and CE apps have to be built to run on the SH4 CPU so you can’t just use any ordinary apps
@@NaokisRC do you mean windows ce exe have to be for windows ce and right arch?
But idk if desktop is hackble with platform builder and build with desktop environment(this does not come with sega)
i have a lot ideas what i wanna do with this devkit
25:40 a 3D version of the dreamcast bootup screen should have appeared when it said "please wait." thats weird
Jus found one while dumpster diving 👍🏼
Is the intro song a remix of After Burner?
Indeed it is!
I wouldn't know the first thing to do if I came across this system, and I have no idea what's going on. I'm just here.
Still thinking in 2024 ❤️
25 years ago, bruh.
I imagine that someone else might’ve pointed this out already and I didn’t see it, but Win2k is based on NT, whereas 98 is not. So that’s likely the difference.
The software and hardware works on Windows NT 4.0
Very cool and informative video. I hope I can find one of old sega consoles, it is a very interesting part of video game history. (Post scriptum: can anyone say the name of the background song 4:00 - 6:50 ?
Its a custom version of one of the songs from Hang On or Super Hang On I made a few years ago. I cant remember the track name, sorry.
@@NaokisRC Thank you, it’s a pity that you couldn’t remember the name of the song, but I’ll try to look for the original. Thank you very much for the answer.
7:58 Is that Sonic on the GD-ROM drive's sticker on the left?
Yes. Service sticker for Sega Amusements in the UK
I have a 200 plus page manual if u want it. Just gimme a week to photocopy it
No need, its all available on github 😅
what the song 3:05 i cant find that ? :(
Its my own rendition of After Burner 2’s second stage music. I will look to putting it up for listening in future
Don't unplug the VGA cable while it's powered one - many devkits smoked doing that :)
WoW
3:08 This has to be some sonic music in the background. You know the copyrights expired on it haha.
Its my own rendition of After Burner IIs second stage music. And I prefer to make my own versions of some songs!
The model for Series X...
A Sega Cortana?
I see a sony chip :D 6:05
