My Snes Experiments
00 - Blue Screen
It's just a blue screen. Pretty cool, right?
01 - switching primary colors
It rotates between red, green and blue every second or so. No real loop.
02 - loop counter primary colors
This one actually uses a loop counter for what the 01 does
03 - bitwise rotation mood light
This one is supposed to rotate a binary block of #$1F (00011111) through the first two addressed of CGRAM, I ran into some pretty hefty problems trying to do it in a direct way, the 7th bit of the 2nd byte of GCRAM would reset inbetween frames, so I had to use local RAM to store essentially a "copy" of those addresses - otherwise the screen would just turn black.
