I downloaded many Arcade Roms, X-Men, Teenage Mutant Ninja Turtles, The Simpsons, Marvel Vs. Capcom: Clash Of The Super Heroes, Captain America and The Avengers, Samurai Shodown IV - Amakusa's Revenge / Samurai Spirits - Amakusa Kourin, Metal Slug X - Super Vehicle-001, Street Hoop / Street Slam / Dunk Dream, King Of Fighters '97, Teenage Mutant Ninja Turtles -Turtles in Time, X-Men: Children of the Atom, and X-Men Vs. Street Fighter. Their all in the same folder, but the problem is the only ones MAME reads are the ones that are in BOLD text above^. but the Teenage Mutant Ninja Turtles one it reads says it wont work so I'm confused. Here's my questions, what happened to the roms I downloaded that MAME isn't reading? and If MAME can't play them then what can?, and lastly why won't Teenage Mutant Ninja Turtles work?
I'd like to add that I have the most updated MAME, so I have no idea what the problem is. Thanks for all your help.
