Pokemon Diamond
===============
Everything seems to work just fine (although there are some minor video glitches in both linear and nearest mode - short black line here and there and in linear mode some trees seem to have transparent leaves).
Game runs at 40 fps and that i believe is fine with the original, but for somebody used to play pokemon in VBA at 500% core speed and some frame drop, it actually is painfully slow. Also I can't see any save/load option - that'd be quite useful as well as already mentioned frame drop or core speed regulation.
