I have searched high and low for a compatibility list for the the mame emulators on the market right now and have found nothing useful! I did the research myself and the results are astounding. Tiger mame easily defeats jrioni's jarcade and cps2hd. I paid for both of jrioni's apps and was able to get TMNT to work on jarcade, which was wonderful news for me; I couldn't get them to do jacksquat else. I downloaded tiger mame for free from the marketplace and now have the following working roms on my Epic 4g: The Punisher, Battle Circuit, Vampire Savior- the lord of vampire, Armored Warriors, 19xx- the war against destiny, Willow, 1944- the loop master, Mega Man 2- the power fighters, Alien vs Predator, Street Fighter Alpha 2, Breakers, Metal Slug 4, Blazing Star, Double Dragon, Super Puzzle Fighter II Turbo, Super Gem Fighter Mini Mix, Pocket Fighter, Eco Fighters, Capcom Sports Club, Street Fighter Alpha 3, Captain Commando, Ring of Destruction, Ultimate Ecology, Progear, Marvel Super Heroes, X-Men vs Street Fighter, Mars Matrix, Giga Wing, Cyberbots-fullmetal madness, Alien vs Predator, Batsugun, Karate Blazers, Turbo Force, Aero Fighters 3, Pang! 3, Three Wonders, Nemo, Dynasty Wars, Mega Twins, Strider, Mighty! Pang, Sengoku 2, Sengoku 3, Panic Bomber, Neo Mr. Do!, The Last Blade, Real Bout Fatal Fury 2- the newcomers, Donpachi, Dodanpachi, Baseball Stars 2, Knights of the Round, Shadow Force, Robo Army, Power Spikes II, Ninja Combat, Marvel vs Capcom- clash of super heroes, Mercs, League Bowling, Legend of Success Joe, Knuckle Bash, Garou- Mark of the Wolves, Goal!

You need to download the Neo Geo bios of course and the bios for PGM System I think. About 5 or 6 of the games mentioned above have sound issues, but the rest of the roms run fast and perfect on my Epic 4g. I downloaded all of these roms from one specific site that comes up in google I believe. If you need I can send you the name of the site. Hope this helps!
