Works with GB Studio v1.1.0+ with saving if you wish to develop your own game. Check this list of Gameboy games to see the ROM/RAM size and MBC type your game will have, you would be looking for MBC5 games but most MBC3 games should work and a few MBC1 games may work.
This cart works on every Gameboy system – GB, MGB, GBC, GBA, GBA SP and the Game Boy Player. Games that require more than 4MB of ROM won’t work.
Each unit is assembled in house and is tested on a Gameboy Advance.
ROM: 2x 2MB Flash (M29F160F)
FRAM: 32KB (FM18W08)
MBC5 (with ROM banking range 0x2000 – 0x3000 to allow for some MBC3/1 games)
The PCB finish is ENIG.
Pokemon Pinball save issue
With Pokemon Pinball we found that it didn’t use the first bank of the save chip, it was the 2nd or 3rd 8KB bank but the original game was limited to 8KB.
You have 2 choices:
1. Bridge the top pads with solder to lock the save chip to 8KB. If you flash other games, you may have to de-solder this bridge.
2. Make a backup of the save file you wish to restore. Open a hex editor, copy all the contents and paste it into a new file 4 times so the file size will be 32KB and then restore that file. In FlashGBX, change the save type from 8KB to 32KB before the backup or restore.
