Like 2eyez hinted at, all Neo-Geo emulators can switch between the Neo-Geo Arcade and Neo-Geo Console, thanks to the hardware being identical. You can switch between Console and Arcade by simply enabling either one in any given emulator's menu, or if you have the Universe BIOS, through its options as well. Take note that playing certain games in Console Mode automatically censors certain aspects of the game, unless you use cheats (built in to the Universe BIOS usually) to enable things like fatalities and blood. Many games are affected by this, ranging from Metal Slug to Samurai Shodown. As far as emulators go, take your pick: MAME, Kawaks, FBA/FBA Shuffle, Nebula. I really wouldn't recommend NeoRAGEx in this day and age, because it uses non-standard sets and does not support encrypted sets (all post-1999 games starting with King of Fighters '99 and Garou: Mark of the Wolves). Like you are undoubtedly aware, it's hopelessly outdated nowadays and its unofficial hacks can't fix its most crippling flaws. I wouldn't recommend Nebula either, because it hasn't been updated in ages and doesn't support games like Samurai Shodown V Special, and has other issues with detecting even official sets. Also, most if not all emulators these days have the option to only show the games that you have, instead of all the games that the emulator supports. Personally, I use FBA Shuffle because certain aspects of other emulators just plain irk me. Your mileage may vary. P.S. Before you go "omg online play!11", AFAIK, said online play in Kawaks is through Kaillera. Said implementeation is poor, not to mention ancient, and only works properly for the select few, which has made me dub it "something Satan coded just for teh lulz". Someone correct me if I'm wrong, though. Few have dared.
