Wow it's jut not liking my BIOS or MS1.
*sigh*, and I cannot for the life of me track down a clean copy of the BIOS so I can even see is my roms work. MS3 looks like it works though.
edit:
nev3rmind i got it, one of the bios files needed to be renames (sfix.sfix, the second I was missing). Metal Slug 3 runs but some of my roms are corrupt. I'll get this all straightened out.
Thanks guys.
