GBA BIOS Info
In order for GBARunner2 to load titles, a dump of the GBA BIOS is required. Newer builds of GBARunner2 (which come with the latest release of TWiLight Menu++) have Normatt’s Open Source BIOS built-in. However, because it is not an exact copy, using a dump of the official BIOS increases compatibility. You can dump an official GBA BIOS with one of the following methods.
Dumping Guides #
- Wii (not family edition)/GameCube + link cable dumper
- 3DS using most Virtual Console titles (Can’t be GBA or non-Nintendo (Game Gear) Virtual Console Titles)
- GBA or DS Phat/Lite with a GBA flashcart
After dumping the BIOS, it must be renamed to
bios.bin and then should be placed in
sd:/_gba/ for GBARunner2 to read it.
You can verify that your BIOS is a proper dump by comparing it with the following checksums:
If you don’t know how to obtain a file checksum, you can use an online checksum calculator.
