Ah sorry, I suppose there should be a changelog from the bounty release. Here you go:
-Mostly finished APU (audio) implementation
-Major PPU (graphics) fixes
-Substantial mapper optimization
-Added savestates
-Added settings menu and control remapping
-Various menu improvements
As for the game covers, it's not a huge deal for me personally, but if enough people want it I'll look into it eventually. Right now mappers are a higher priority for supporting more games!
