Running
To use NanoboyAdvance, you will need a BIOS file. You can either extract your own or obtain an open-source alternative from online sources (https://github.com/Nebuleon/ReGBA/blob/master/bios/gba_bios.bin). The BIOS file should be named bios.bin and placed in the same directory as the executable. Please note that an alternative BIOS may not offer the same level of accuracy as the original.
