Thank solidius23, but I may have solved my problem. I did this already with another rom, but I guess it must have been a bad-dump. I changed the extension from.mgd to.smc and it worked It didn't work last time, I promise!!
Hello all, I didn't really know which forum to place this question in, but what are roms with a.mgd extension. They come up in GoodSNES, but I can'r run them from any of my SNES emulators! Any help/ideas would be much appreciated.
