help with snes rom

[omegatron]

ok i have a rom supermarioworld ) which i own the actualy game) but the rom has no file extension... just the name and the file type whn i go to properties is just FILE.... How do i convert this to .smc so i can use it with snesstation???

if you can't just manually add .smc, or maybe .zip at the end, it's probably a bad file.
