I'd be interested in this if you can get other games loaded on to it. There's loads of old classics that aren't there that I'd want. The Arthur Pendragon games (Staff of Karnath, Entombed, Blackwyche and to a lesser extent Dragonskulle), Beach Head, Spy vs Spy I and II (never played III), Green Beret, Ghost N'Goblins, Chiller. Some old school Hunchback, Jet Set Willy, China Miner. The list goes on and on. I do have pi with retropie on there but the C64S emulator menu system is real clunky.
On a completely separate note, Impossible Mission in a browser -> Mod Edit: No links to emulated games not in the public domain I'm afraid
