My friend just gave me and emulator and this rom today am i am so crap at this game im stuck on the mist dungeon*hangs head in shame* and cant find my way throgh it any help please

Can you not see? I had the same problem when I played it on the rom. The mist is too thick to see through, not like on the actual SNES game. You just have to change some settings on your emulator. I don't remember which ones exactly, just screw around with the video options.
