Just installed the Super nintendo emulator MeSNEmu from Cydia Geeks and I found out that they don't have any pre-built ROMs for the iPhone. I don't know where is the proper place to get the games like Mario. If any of you have epxerience with this, please help me out. Thanks

Btw, is emulator even safe to use on iOS? I don't find any from the App Store that's why.
