Rockboy returned error (sansa Fuze v2)

[metoob]

im using build 3.9.1 and when i start any gba games it says: invalid opcode 0x%02x at address 0c%04x, rombank = %d
then: plugin returned error *quits*
also some of my png files say "invalid signature" but u dont have to answer that i can live with it.
ive tried a few different roms. and ive seen people use rockboy on a fuze v2, so what happened specifically to mine to do this? D':

The ROM you're using simply doesn't work with the state rockboy is in. An emulator is almost never perfect, so there will be files it doesn't work with. Besides, gba is Gameboy Advance, and rockboy doesn't support those (it only supports Gameboy and Gameboy Color). The manual has this information ...

whoops
i meant gb; i was playin gba games on psp at the time
and it worked on my freakin sansa clip, and at full speed man
i was hoping for some information on the error and/or plugin D:
and i know its not perfect but should moving to a newer machine worsen the compatability? ill try some more roms and tell you what happens. thanks for listening ^^
