I may have found a bug, retroralph.
If I put a fair few roms in either the nes, or sms directories, the emulator just crashes when you click on play game. I'm finding that anymore than around 50+ roms and it just crashes, for me anyway.
Quite a few roms are also missing from the database, just for example, the sms rom "Astro Warrior & Pit Pot (UE)" isn't recognised.
Also, is "Input" working ? Or is this sort of a WIP ?
