GBARunner2 is a hypervisor that runs GBA games on DS/DSi/3DS in DS mode.
GBARunner2 has the open source bios of Normmatt integrated, with some small modifications. A GBA bios is thus optional, but can be used to improve compatibility with some games. Always try with a valid GBA bios before reporting that something doesn't work! Compatibility testing should as such also be done with a bios. You can put the bios in one of the following places: /bios.bin, /gba/bios.bin or /_gba/bios.bin.
A valid bios should have the following checksums:

GBARunner2 will always be free software and you'll never have to pay to use it!
