Re: Test: the cycle
Yes, between this, the rainbow example (which I can get correctly in JACE if I intentionally mess up some timing settings), and Money Munchers title screen (which I can also get working but unfortunately different timing settings than Money Munchers) I have some great test cases to use.
I think that I must have a timing mismatch in my code that varies by graphics mode. But it was fun making some timing adjustments surface in the configuration (I <3 annotations!) Just so I'm clear: HBLANK is 25 cycles long and starts at the beginning of each line, or the end of each line? Also, what is the video scanner picking up during that time? Say that 0 is an offset relative to the leftmost byte on a row -- would it be -25, 0 or 40? Money munchers seems to look **perfect** when I assume HBLANK starts at 0 on the current line.
It's nice to know that JACE *can* render this stuff in some plausible circumstances, because that means I can figure out where things are off and fix it now.
side note: I fixed a big nasty horrible bug that causes JACE to crash when configuration is applied -- and now it is really damn stable for a change. You really can change out hardware while the computer is running. Prodos gets really confused though when you add/remove disk interface cards, as well it should I suppose. :-)
