Hi, i had the same problem before, also with my 8GB SD card. What worked for me, was to formate the card with Minitool Partition Wizard to FAT32 Primary.

I got it sorted out now, thanks again.

I now tried to change the .BIN to .bin, but still I can not play my pce cd game, I converted a iso into a bin file, and created a new cue sheet for that .bin file. On the Recalbox 4.0.0 beta 3 I can not even see the .bin file. It only showes me the cue sheet. On my old 3.3.0 beta 17 I used the Iso file and the cue sheet and it showed me both in the on screen menu. And by the way, thanks again for the reply, FDS now works for me. It was the bios file, that I had to rename.

Ok, thanks, i give it a try.

Hi there, is anybody else having problems with PC Engine and Famicom Disc System games? They worked fine on my Pi 2 under Recalbox  3.3.0 betas, but on my new Pi 3 on Recalbox 4.0.0 beta I cannot play them anymore. I have the same bios files in place and the same roms/bins. Does someone has a idea?
