Thanks a lot for testing this!

Does ignored mean that the register value doesn't
change, or just that the color on screen doesn't
change?

I can easily make it so that byte sized ST reg write
isn't mapped to TT registers, which Hatari uses to
actually change its own palette, but I don't know
how to block byte sized writes (and the old value
isn't anymore around so that it could be restored
to the register after the write).

Philippe?

Working already. :-)

OK.

I think those should work (like they now do), because
4getful TT-version is using them.

Why not, tests are always appreciated!
