Dump the GBA BIOS using Multiboot.

I created a program to dump the GBA BIOS using the Raspberry Pi Advance Expansion Board.

As it is now, the tool that can be sucked out is gone, so please use it if you want to suck out yourself.

I use the multiboot program of akkera102 and the example of DebkitPro.

 

How to use

 

  1. Connect communication port of expansion board and communication port of GBA main unit with communication cable (for GB pocket etc.)
  2. Start GBA with no cartridge inserted
  3. COMMAND

$ git clone https://github.com/cubicstyle/biosdump_rpa.git

$ cd biosdump_rpa
