The jagginess is intentional (and its funny cause your the 5th person to use that EXACT word..). It's because we now have framebuffering.. which sets the screen at a much lower resolution. This is fixed by adding framebuffer enable=0 to the bottom of gles2n64.conf (read second post on how to open this).

I'm off to get my haircut. Will upload latest, with saving, new gles2n64, and accelerometer support when I get back. While I'm gone.. anyone want to upload a keyboard mapped blight_input that the think is better than the default?
