Nebula also plays CPS2 (Street Fighter Alpha series+), CPS1 (original Street Fighter 2+), some newer Konami games, Polygame Master (similar to Neo Geo) and soon Model 2 emulation (Virtua Fighter 2). NeoRageX hasn't been updated in 2 years and doesn't support many of SNK's last games, except through hacked ROMs. Actually, Nebula is the most advanced Neo Geo emulator available.
