Can't open files.

[CastletonSnob]

I downloaded a SNES emulator on my Android-powered Digiland, but it says, "can't open file". What do I do?

read up on the emulator find out what files it supports, SNES rom dump can be in a few formats though most can be converted easy enough with the correct tools, but you would need to do that on a computer

also the emulator may or may not support compressed roms ir only certain types of compression
