Decompressing random levels can take up to about 30 frames. So the TV won't get any VSYNC during that time.

Here I'll miss again a least one VSYNC (overscan time ~2500 cycles vs. decompression time ~7000 cycles). Same problem, isn't it? Are there any other games (except Chess) which are blanking the screen for longer times to do something very complex? > BTW seem to be using adresses $fff8 and $fff9 in your game.
