Hello guys i installed Recalbox on my Pi 2 and i have installed 0.78 roms for mame. I have downloaded a full set and installed roms on Mame folder but none of them work. I figured i had a wrong set and downloaded another .78 set and just to be perfectly sure they are compatible i run them through clrmamepro. Again no games run. I click them, screen goes black for 3 seconds and i'm back to game selection screen. Any ideas would be appreciated since i really want to make it work. Thanks in advance.
