Homebrew GBARunner2

[admin]

GBARunner2 is a hypervisor that runs GBA games on DS/DSi/3DS in DS mode, basically like Nintendont does for running Gamecube games on Wii.

Usage

• Place a GBA bios on your sd card. Either /bios.bin or /gba/bios.bin will work.
  • Note: Do not use Normmatt's open-source GBA BIOS. It won't work, as many patches are applied at fixed addresses. The right checksums are listed below.
• If you have a gba folder on the root of your sd, this folder will be opened by default
• Do NOT use SRAM patches unless stated on the wiki. They cause problems with the internal patching of GBARunner2 and may actually break saving.
• If you are using GBARunner2 with TWiLightMenu on a DSi or 3DS with the SD card, make sure you use the dldi on ARM7 build

If you want to use existing save files, they should have the same name as the gba file but instead of .gba they should be .sav (so the save for mygame.gba is mygame.sav).

BIOS Checksums
The BIOS used should have the following checksums (checking one should be enough):

• CRC32: 81977335
• MD5: a860e8c0b6d573d191e4ec7db1b1e4f6
• SHA1: 300c20df6731a33952ded8c436f7f186d25d3492
• SHA256: fd2547724b505f487e6dcb29ec2ecff3af35a841a77ab2e85fd87350abd36570

You can check the MD5 with WinMD5Free for example.
