I have mame on xbox and I have the Killer Instinct .chd and .zip
files and I want to know is there a way to play this game on xbox?
Also can Street Fighter vs Xmen be played on xbox. I have several Neo Geo
games and they work perfect so I thought that maybe these will work also.

i have it on my super nes emulator and it works great
maby u have a bad rom

No the arcade version of K.I.

well i can read thats why i stated that i have it for my xsnes emu and your title said can u play it on your xbox....... and yes u can

This has been covered before. KI is just too big of a game to emulate on the Xbox. It takes up more memory or something than the Xbox has. The only way you can play it is on the SNES emulators.

Thanks!
