I recently installed PiMame on my Raspberry and it perfectly work but i have some questions. I want to use Roms for PS1 and SNES but i don't know what are the files extensions of the file i have to put inside my Raspberry (i tried to get one Roms from a website and i got a .bin.ecm (ps1 rom) and a .smc (snes rom). Are they good or what ? Another question, should SNES roms be in /roms or /snes/roms ?
