60 fps video using SIDE 2

For the "stupid Atari tricks" section: by abusing IR mode 2 addressing, I figured out a way to get ANTIC to DMA playfield data straight out of an IDE interface of a SIDE 2 cartridge. This allows reading off the CompactFlash cartridge at 360KB/sec instead of 86KB/sec and in this way I was able to boost the frame rate of my old video player all the way to 60 fps, while still playing 15KHz audio:



Kind of useless other than for novelty purposes, but I was surprised that the hack worked.
