Mercuy126

This may just by be me but I don't know how to patch or anything ( I'm new to roms and emulators and this type of stuff) and what happens is that I go to run it and it just appears black the emulator that I'm using is the zsnesw and the read me is confusing to me so if anyone can help me with this it would help out a lot ( also again I'm new to this stuff and it might be something very simple but I'm just starting)
