I followed the instructions to get the retro games, but I can't figure out how to get the correct emulators to work for the different gaming systems. I only have 3 available after "downloading" and "launching" a game. The 3 that I have are after following all the instructions are: Amstrad - CPC (Caprice 32), Arcade (FB Alpha), Commodore - C64 (Vice C64). A little help? How do I get more emulators?
