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
- GBA/DS/DS Lite with GBA flashcart or 3DS
- It is not possible to dump the GBA BIOS on a DSi
- Wii (not Family edition)/GameCube, GBA, and link cable dumper
After dumping the BIOS, it must be renamed to bios.bin and then should be placed in sd:/, sd:/gba/, or sd:/_gba/ for GBARunner2 to read it.
You can verify that your BIOS is a proper dump by comparing it with the following checksums:
GBA/GBA SP/Game Boy Micro/Game Boy Player:
- CRC-32:
81977335 - MD5:
