SNES rom files.....

Hi, I just downloaded my first emulator today, so forgive me if this is a question with a really obvious answer because I am not at all familiar with this stuff and I'm not really even that great with a computer to begin with x)

So I downloaded a ZSNES emulator onto my laptop and also downloaded a Super Mario RPG rom. The rom has like 13 different files in it though. As long as I found one files that seems to work fine (I did), can I delete the other files? Or is there some reason that I would need to have the other files? Once again, sorry if this a simple question.

The rom should be one file. That zip (probably) contains many versions of the game. Just keep the one you want and delete the rest.
