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 TWiLiight Menu++) have Normatt’s Open Source BIOS built-in. Because it is not an exact copy, including a dump of the official BIOS increases compatilbity. 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 (gamegear) Virtual Console Titles)
- GBA (Micro/SP)/DS (Phat/Lite) with a GBA Flashcard
After dumping the BIOS, it must be renamed as
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:
CRC32: 81977335 MD5: a860e8c0b6d573d191e4ec7db1b1e4f6 SHA1: 300c20df6731a33952ded8c436f7f186d25d3492 SHA256: fd2547724b505f487e6dcb29ec2ecff3af35a841a77ab2e85fd87350abd36570
