I've started making a full schematic for the gba, the model I used is AGB-CPU-03. It's still work-in-progress but updated frequently. I could use some help: If you have some time to spare you could help finding flaws or help to complete it that'd be very much appreciated! There are hires scans of the mainboard that I've uploaded to the strip club: http://stripclub.arcade-tv.de/ Also I colorized some signals like GND, VCC, VDD5, VDD3 etc here's bigger file of that: https://picasaweb.google.com/lh/photo/MyyarZgFLNg7ubwwal4GYtMTjNZETYmyPJy0liipFm0?feat=directlink This is what I have until now: I wasn't able to identify all the transistors and diodes by their smd-code, but I made substitute packages with the same footprint. Here's the archive containing the wip-eagle-files, my library and a text-file with all signal-names. https://dl.dropboxusercontent.com/u/27485470/AGB_CPU-03_WIP_20141207.zip And this is my 130MB-PhotoShop-file with all the layers, mirrored and colorized with pins numbered: ]https://www.dropbox.com/s/337m8x6klnb6wl6/GAME_BOY_ADVANCE_AGB-CPU-03_XRAY_PCB_SCAN_ATV.psd?dl=1 Here're some datasheets for possible matches of not-yet-identified components: https://dl.dropboxusercontent.com/u/27485470/gba_datasheets.zip Another great ressource for gba-info: http://problemkaputt.de/gbatek.txt So, if anybody would like to join the party, be my guest!
