Thanx for testings.  It helps for sure.
It is little confusing, but as said, ST(E) is not designed with accurate palette color writing timing in mind. So, 1 T state (125nS) variation happens depending on something by powering on. In normal usage it is completely unnoticeable.

I need to inform some people, like S. Seagal and Cyg. First may add wakeup setting for STE in Steem. Second should update hiSteColor for Timing A in 54 color mode.

Here is regular Steem 3.2 with only changed to TimingA:

Just copy it to your Steem DIR and use to see difference. If compare hi-color screens of hard disk adaptations, latest ones, you will see that errors are same as on YouTube videos of games. By me, it should be default Steem timing, since most of STE machines are in TimingA in most of cases.
