Hi Ralph! when i press F5 i can get smoother graphic filter...when i press F3 i get fullscreen etc etc will you make a readme for all commands and how to use them? or have i just missed it? will you implement savestate? or the possibility to save in game like a batterybackup (miracle warriors, phantasy star etc etc) thanx again for doing all this

The graphics commands will be in menu form very soon. I don't want any hidden keyboard commands really, anything that is keyboard driven will be in the input section.

For now :-

F2 : Some debug stats
F3 : Zoom when in fullscreen
F5 : Pixel/Smooth filter
F6 : 4 Different graphics filters

I'm going to be turning on save states within a week or two as well, the only reason I haven't yet is because they might break version to version but for now at least SMS/GG/SEGAE will be very stable, NES/MD likely won't. But having version specific save states is probably better than none at all especially when it comes to bigger RPG type games.
