- In this video, I’m revisiting [Side Pocket] to tackle the issues that stumped me before. Did I finally manage to fix it?
I am not a professional nor an expert and I still learning as I go so I may not do things the most efficient way (Or the correct way)

Huge shoutout to @simplemindedsage, @caseycornett5182, @FennecTECH, @Jdc1197, @Fuzy2K, and @TalasDS
for all the Comments and setting me straight about the "Resistors" and giving me ideas on how to diagnosis the game :)
Your welcome. Glad you fixed it. I was sure it was the rom but I am glad I was wrong.
For the Vdd, GND thing. On both sides of the cartridge are big bus bars, which are marked Vdd and GND on the silkscreen.
11:15 diode test actually shows how much voltage the component is dropping. So, the voltage you are losing in the circuit, this is why a common diode will show 600 to 700.
Those are millivolts, btw. So 0.6-0.7 volts which is a number you might have heard before.
Digital multimeter usually will send up to 2 volts, that's why you don't see numbers bigger than 2000
So the mapper was the culprit, eh?
See, usually diode tests on ICs won't return any useful information. Normally, I don't bother with them and that is also why many people just replace the ICs when in doubt.
Good to see you got this thing to work. I'll be gladly watching the rest of this series.
Brilliantly done, congrats on the solve! It'd be interesting to look at that failed mapper chip and see if we could figure out why it was giving the Game Boy CPU so much grief.
Awesome! Glad you were able to get it working! I'm also glad your GBA SP is working fine too :)
Also, I love the googly eyes on the multimeter probes. It makes them look like a pair of squids XD
Yo. The fact that he pulled that game out in the beginning and then the SP turned on as he was opening it. That was freaky. Something was definitely bogging down the SP and shorting out somewhere. I'm only like 5 minutes in the video and I can't wait to see what the fault is
I was not expecting that
I think that might have been a quick cut.
Just a tip from one amateur repair man to another, if your hot air gun has an airspeed control and you're having trouble getting a chip on to the board, turn the airflow down, it definitely helps, especially when you're dealing with tiny tiny components.
nice job! i can see you are new at soldering. you really need to get all the solder that is still on the pads of the PCB off of them! so you have a nice flat surface to work on. then your chip is not jumping when you try to put it on it's right spot. you need the good old copper wick (solder wick). buy the one that have flux on it and if it stick cause by error you soldered it to the PCB never pull on it! you de-solder it with your soldering iron you can also add some flux to make it works better and try on garbage boards so if you destroy them you don't really care. continue that way you are on the good path trying to fix electronic stuff is the best way to learn!
Thanks for the comment! I'm here to learn and grow, so every comment pointing me in the right direction is very much appreciated.
@@HopefullRepairman oh yeah i been really bad at soldering before i become a pro! and if ii can do it, everyone can do it
Dude congrats, it was great seeing you solved that problem.
I'm super thankful for all the help and advice I got it helped a lot. I also learned a lot of working on this game. Thanks for watching and commenting!
I love the song from this game. Super nostalgic chiptune for me
I see you're struggling trying to put that chip back on. That I learned when working with small components. Dabbing down some flux to stick it in place so it doesn't go hopping around. And then cleaning your tweezers
Good idea I'll have to try that next time
@@HopefullRepairman When I need to hold a small component in place I find Mechanic's UV50 flux paste works well for that. The downside is it takes a bit more q-tip and IPA to clean up the gooey flux afterwards.
@@HopefullRepairman Your actual main issue was not removing all old solder first, trying to set tiny legs on top of 30+ solder hills it will obviously slide off 1 way or the other, in the future flux and copper braid off all old solder from the pads so the pads are flat, then clean with ipa then flux pads and set chip and then tack 2 opposite corners.
@@icey_projects I'll have to try that next time thanks for the advice
One thing to know about the GBA is that if gameboy color or og games cases are too damaged it won't hit the switch to tell the GBA that it needs to switch to gameboy mode
Great video again !!!
Hi, iwould really love to know whether the Chip would still work on Play Action Football. The Reason is: i watched a lot of repair videos and learned that Gameboy games for some unexplainable reason often get a loose connection on the left chip on its right top side.
So maybe a simple reflow of the legs would have fixed this, too. So soldering this again on the PCB of the football game might work. It could also not work, but just for the sake of science... 😀
I'll have to find a replacement capacitor first, but that would be cool to see
Great work. Try preheating the board before placing the chip. Might help.
Thanks for the advice. I'll keep that in mind for next time.
the soldering gave me an aneurysm
Did I speed it up too fast? Or was it too much jumping around?
@@HopefullRepairman Some people just refuse to acknowledge that people don't start off as an expert in what they are doing.
The normally-relaxing music over top of 21:23 for 3+ minutes...~*chef's kiss*~ If it were written into a screenplay, it would be considered too cliche' and hacky
Nah, for a newb he did great!
When measuring capacitors it is never a good idea to do it in circuit since other stuff affect their reading and as you shown in video it jumped down to zero on the dmm showing a dead short. just remove the cap or lift one leg on it and measure the cap directly and if it still shows a zero value in diode test it is absolutely shorted, it should also read a rather high ohm value too.
and when re-mounting ICs to the board it gets way easier if you remove the old solder on the board first with solder wick and then tack one corner or two on first. it won´t slide down to the side if there is no solder to slide on.
last note is that you can also measure data lines for shorts too and not just VDD and VCC and you may find more things not correct that way.
I have a Sega genesis game that have the same issue and I checked everything so it is absolutely one of the chips that died on that one too
Thanks for the info!
Do you take mail-ins? I have a water-damaged gameboy pocket motherboard
Unfortunately, no I don't. I lack the skills and the confidence to accept mail-ins for repairs. I'm sorry your Game Boy pocket is broken. If you are interested in trying to fix it yourself, I could recommend my mate Vince's channel. He worked on a corroded game boy pocket. Here is his video on it if you are interested ua-cam.com/video/05fpxN9jpug/v-deo.html
@@HopefullRepairman That is understandable. I had considered just transplanting the iccs into a replacement motherboard that float around in aliexpress. It probably also needs a recapping anyways.
