It's easy to get a pack roms on the net and the roms are often labeled differently. So for example say you have Final fight rom for snes does it need to be named in a certain way for mess to see it and play it ?
Second question:
Does mess need bios or certain images to be able to run certain consoles and it's games ? Like in mame you need the neogeo bios to run the neogeo game. I'm hoping it don't need some offical TOSEC set or something like that.
Just to be clear I'm not asking where or how to get any roms/images.
