|  Re: Could someone run test software for me?
Thanks very much for the chart. I don't understand it, but will study it. I assumed that since the crystal is faster on PAL, my code would execute faster. But my thinking was backwards. If my code produces enough delay running on PAL, then it will produce more than enough delay runniing on NTSC.
But, I thought I had tested the relevant possibilities by running the test with a normal screen and with a blanked screen (bit 4 of $FF06). However, even if only looking at the chart's top four entries and bottom four entries, I'm not sure I've done that. I will need to understand what $FF07 and $FF13 do. There appear to be some settings where NTSC runs faster than PAL.
