I'm using retroarch as the emulator and I've imported my roms. What seems to happen is that when I run anything through regular launchbox (not bigbox) it plays a random song from the game but I'm never able to actually load the rom. In bigbox it looks like it's about to load and then nothing happens. I tried reimporting my roms and the same thing seems to happen. I haven't changed the emulator that I'm using and I'll be trying that on my weekend (I work over weekends ) but if anyone has any other possible explanation of this weird behavior I'm all ears. I'm using retroarch for other systems and they seem to be fine and while I know they use other cores it's odd that this would be happening. I can also run my SNES roms in retroarch when I do it directly.
