me pone esto exactamnte. Soy novato y no se que hacer...
Sorry, but gpSP requires a Gameboy Advance Bios image to run correctly. Make sure to get an authentic one (search the web, beg other people if you want, but don't hold me accountable if you get hated or banned for it), it'll be exactly 16384 bytes large and should have the following md5sum value:
a860e8c0b6d573d191e4ec7db1b1e4f6 or 1c0d67db9e1208b95a1506b1688a0ad6
Other BIOS, files might work either partially completely, I really don't know.
When you do get it name it gba_bios.bin and put it in the same directory as this EBOOT.
