I'm working on hi-color video playback together with Cyg and Douglas Little - so it includes hi-color picture displaying on ST, STE machines too. There is one issue what results in small errors in displayings in some cases, caused by different timings in video circuits on diverse machines and emulators. Furthermore, it may change by warming of machine.
Errors look like:

SW for testing: http://atari.8bitchip.info/TIMINGC.ZIP
Mostly testing on STE, Mega STE is interesting. Please, run TTP executable, and enter 1A and look carefully what is on screen errors are not big - bad color dots, mostly at same hor. pos, so like stripped vertical bars. Exit with space, then check other s -1B, 2A, 2B .
If can, do check with cold machine, and later with warmed up - but turn off for short between tests - it is important, because timing scheme sets only by power-up. Then write here which ones looked good, which bad - and when.
My STE, when is cold shows well A or B in 50%-50% cases. When is warmed shows always A correct. Emulators whow B correct (Steem and Hatari). My Mega STE shows correct A or B even when warmed up. I don't expect situation that none will be shown correct, but who knows - then would like to see screenshot of it - but it may be problem if no capture card. Warmed up - it means here after working couple minutes - intern warm of chips is relevant, not that computer gets hot :-)
As presence for people contributing: you will be able to playback something like this on your machine:

It was made with Mega STE and UltraSatan. STE is good too, of course - must run on 8MHz CPU clock. I need to fix some things yet in playback SW, mostly related to diverse filesystems and drivers possible. As already said earlier: this will work only if disk and adapter are enough fast, so min transfer rate is 1100KB/sec. And you need to defragment partition on which large AV file will be copied.
SW and example AV file in couple days ...
