By contrast, I'm finding trying to play games on my Raspiboy via RetroPie an up-hill struggle and wondered what I could possibly be doing wrong?
Example #1 - GBA
I copied gba_bios.bin to the bios folder and some gba roms (.gba) to the appropriate roms folder. Booted RetroPie, the games are listed but none of them work. They either lock-up on a white screen or return to the games list.
Example #2 - PiFBA
Same deal. I copied the bios and rom files to the appropriate folders, ran the games and they all lock-up at a black screen or return to the games list.
I know this isn't an issue with the RaspiBoy but I figured there would be people on here with experience of getting these, and other systems, to work.
Any pointers or advice welcomed.

Cheers.
