i understand now but i need 2 know 1 thing..

i understand everything now but have one question i need 2 ask

does a ROM have more than one game on its file or does it only have a single game per download

thanks for any help

It really depends on a certain host site you're into whether it is one single game being zipped or multiple games in a 7z file format.
