So I've just installed RetroArch on my PS3. Running the update functions ATM to make sure everything is up-to-date. I've been reading for a few hours (here and the official docs), but can't seem to figure out where to put my ROMS. I have NES and SNES Games that I'd like to play, but need to figure out where to put them. Also... Do I need to find the BIOS for NES/SNES? Are they included in RetroArch or even necessary? Also noticed that during online update, RetroArch freezes randomly, forcing me to hard reset m PS3.
