  Nah that would catch all negative results, not just 0xFF.

    This got me thinking maybe it can be used for indexing from 0 - 128 for indexed addressing modes and that begs the question are the indexed addressing signed or unsigned? Apparently they are unsigned, so the trick might be possible: http://forum.6502.org/viewtopic.php?t=1300 http://forum.6502.org/viewtopic.php?t=1300
