Good job! Quick tip on soldering the CPU/RAM -- pre-tinning the pads is likely why you had difficulty lining up the chips. That's not gonna be an issue with hot air since you can just nudge it while everything is molten, but with an iron it gets tricky.
Yep I learned this eventually with chip swaps. If hand soldering, don't pre-tin the pads. Just line of the pins, tack on a couple corner pins to hold it steady, and then drag solder each side.

FPGA is going to be a necessity in short order. As good as solid state electronics are, time will ultimately win out and 30-40 year-old hardware eventually will burn out with even moderate use. Love that these exist, but we really need a new FPGA Gameboy Advance chip before long.
There's an open source version of this but with the GBA SP switches and NOT $70 and constantly out of stock called the AGZ-CPU-01 just for anyone who wants a cheaper solution that has better buttons and can be modified to your needs so long as you have some electrical engineering skills.
That project seems to be a one off with no releases of any kind. I can only find a GitHub page and a few articles on it. Does not seem to be open source
Ok Jake, People reading these comments, the best trick to lining the RAM and CPU up is using a piece of tape. I use kapton because its at my station. Tape it up, tack the corners then solder all the pins without bridges and its painless.
This definitely seems like a good experience step towards doing a Pocket Color or DMG Color mod. I recently got myself a hot air station so it would be some good practice. I just need a GBA with a shot board and good CPU/RAM.
I saw something on ... Macho Nacho? regarding the LEDs you can set one then then apply that color to all the LEDs. Not sure if its a different revision.
Did they ever fix the headphone mono audio. GBAs can do stereo audio with headphones, I heard people mention this issue but no acknowledgement by Funnyplaying or fix.
Hopefully we see more of this kind of thing in the retro scene. I feel like a lot of "too far gone" systems could be saved this way (I have a few. I'm too much of a pack-rat to throw out what could be vital parts)
I can't think of many PCBs that are so "too far gone" that you can't just patch them up in-place. But i think we also need to develop better techniques for some of the faults. Cartridges are a strong case though, many of those PCBs would definitely benefit from a full replacement. But you should also order real 30µ hardgold bevelled edge and not the usual ENIG (electroless nickel immersion gold), which is not something that happens a lot. Console PCBs with ENIG are just fine, i wish you could get hardgold on rubber button contacts but i don't think you can.
I would love to do this, i just dont know how to solder. Plus fp is sold out of the purple board. The glass shell with purple board and buttons would be nice to have
I am currently trying to see if I can combine the laminated screen kit from funnyplaying, the HDMI Out through USB c docking mod, and this motherboard. Already combined the first two I listed (yes I know there's a mod that does both now; that's NOT the one I have, lol), but now I need to see if there's a way for the new motherboard to connect to the HDMI docking mod, because the ribbon cables for that mod are designed for the original motherboard, not this one, and I already know the button solder points will be a little more tricky to get to. The main thing I have to look into is that the HDMI docking mod has you desolder a fuse from the GBA (since it uses a fair bit of extra power), so I am wondering if anything needs to eb done with the funnyplaying motherboard, or if it just works by default with no fuse removals.
I had tons of GC Gameboy Player… could we do this mod with it? Because could be awesome for all people who has GBP and lost the dvd to play with it on GC.
Do you know if there's something equivalent for the Gameboy pocket? I saw there are the schematics I could send to pcbway, but the price in the end is higher than grabbing a couple of used GBP on ebay and pray
This might be what I need. Been looking at getting a GBA for a while, but working ones are too expensive considering I plan to fully mod it anyways. Are these chips the same as an SP? I have a GBA SP that's pretty beat up, would be cool to give it a new life.
"32 pin GBA Custom Upgraded Motherboard Replacement GAME BOY ADVANCE REPLACEMENT MOTHERBOARD The original parts have been moved" from AliExpress. Is this a good to go full replacement that just needs a screen and shell?
Could you not have just used hot air to resolder it after tinning the board and chip? Edit: I saw a bunch of people ask the same and saw your answer. Love the apple-watch btw, the nike band is such a good look, main reason I went for this version
The next step is actually FunnyPlaying building a FPGA motherboard like their GBC one. Then we can finally get rid of the future issue where we will lose CPU units since they are not made anymore.

Problem is we don't know the logic/gate net of original hardware that you're trying to recreate in most cases, there's only a few pieces of hardware where we have a high degree of confidence. Even reverse engineering original chips by decapping occasionally results in bugs from misreading, since you're more guessing the structure than actually seeing all the etch and material layers, some of which can be well hidden, and people can potentially make mistakes when marking up embedded mask ROMs sections, and then you rely on a potentially brainfarty human programmer translating the potentially faulty net into the programmable logic, so cycle-exact software emulation and logic gate level recreation can have the same accuracy issues. A particularly tough problem is buses which are occasionally tristated on all sides or which have interesting transition behaviour - this is say the reason C64 PLA replacements work just fine on old GAL chips and some old CPLDs, while those using more modern chips and the same exact logic function don't match real hardware behaviour. Decaps almost never result in a complete transistor by transistor markup and read; instead they're used to verify assumptions and clear up doubts, but not all assumptions will be verified. The amount of manual decoding that would be needed is just too much. Generally projects target the existing game library, and can achieve extremely high compatibility coverage, but say new experimental/demoscene code can still reveal undiscovered differences. Some approaches are just fundamentally different. Like say making a synthesizable representation of classic Yamaha FM chips would result in a prohibitive footprint of FPGA used if you did it like it is taped out on the real IC, by replicating the channels. Instead you only create one channel, give it some extra flexibility, and just run it several times faster with buffering in and out. So that is very certainly not replication. I doubt any FPGA project ever will try to exactly replicate Megadrive's slightly bonkers reset logic which results in several ICs being out of phase with each other by different number of cycles every time. It's fundamentally parasitic analogue behaviour. Sure you can make digital emulation of a similar effect but it won't be a replication then. There is basically never the case where original code that was used to prototype the original system using FPGAs got preserved and is available to us. A huge advantage of FPGA systems is high timing determinism (not subject to the whims of the operating system) and latency which is true to original systems.
