I'd like so much use MESS for C64 emulation that you have no idea. I'm thinking at the possibility to use OpenGL shaders and so on.... but when I launch a cracked game and see how MESSY is the intro of the cracker group, I start to cry and close all immediately. VIC-II video chip features are so well documented since at least 15 years. The firsts accurate C64 emulators appeared around 1999-2000 if not before, so I find quite absurd to see that video bugs in MESS today. Probably is better add support for XBOX in MESS than try to emulate a 30 years old computer. Probably.
