Hm, I picked up my droid to play a little NES river city ransom a
second ago, when it hit me.
Modern emulators have LEGENDARY 2d shaders.
Have a look at the dosbox source tree for a whole mess of GPL implementations.
I know there's some shader versions as well, I'll try and dig some up;
if anyone shows interest in getting high quality scalers directly in
wayland (which sounds like a *REALLY* good idea to me.)
2xSaI or Super Eagle scaling of any window to fullscreen would be pure
love for Ten-Foot-Interfaces on wayland. Wayland backend for MythTV?
Suggested aspect ratio should also be passed; in case the user *asks*
to override it (Eg, yes, I really *do* want to scale that 4:3 to
widescreen. *click click... click... click click* Ahhh.)
