I just wanted to comment that you linked to Krestology instead of Krestage, but you already edited the text.. ;)

Krestology seems to work fine for me. Same FW used. U64 Elite 1.41 3.10c

I made a short video from the first part playing:

Oh well, I forgot I had the Turbo Control set to "TurboEnable Bit" because one of the demos supported it. If I turn it completely OFF then Krestology works perfectly. Sorry for this. Demos should be tested with Turbo completely off, not even d030 should be enabled.

In the past Gideon mentioned that when filing these type of bug reports, it would help a lot (and save a lot of time) when you isolate the code in such a way that when he runs the programme it starts where the issue starts.

Are you using custom roms or vanilla roms? Any other customizations or cartridges / peripherals attached to / enabled on the U64?

I accidentally left on "TurboEnable Bit" in the U64 settings, aparently Krestology trash-writes to $d030 and enables turbo :) Sorry for the false report.
