Alright so I have a RPi B+ model that I have installed rasbian and then piPlay on. The issue is, when I put .zip rom files into the roms folder for mame4all, non of the games will work. Also, I dont see a directory for games that might run on advanceMame. So simply stated, I would like either an explanation of how I can get this to work and what type of roms I need (as I know there are different formats), or an alternative method to emulating old arcade games on MAME.

Thank you in advance!
