I think it's the name of the team that hacked NRX to allow those games. I tot it is an emulator Oh well..... Well, it is an emulator; EGCG NeoARGEx is it's name. EGCG is the name of the team that made it. Last Exile: 3. No, one loader will work for all games. 6. No, but like James said, if you only care about playing the games rather that correct emulation, stay with NRX. Personally I could never get kawaks Loader to detect my sets that I added into the DAT. So I switched to Nebula Loader and it works fine. If you want to play you NRX sets in Kawaks Loader/Nebula Loader, so can do so without getting new sets just by modifying Asr.dat or Neogeo.dat
