I tested the version before the last update, which probably only runs with 16 colors. And now again with the current version. I also applied the patch. I didn't notice a version with 64 colors there. If there is one, I'll be happy to test it again. What I did notice, however, is that the frame rate drops a bit in some complex scenes with lots of enemies, in contrast to WinUAE, but it is still fully playable.

(EHB) Extra Half Bright=64 colors.
It would require a very fast HDD and in the absence of other HW that we could test it on, so I can say that it will definitely run on Vampire. You can find it under the name StarDustWarsVampire, but before download...."Look at The Size of That!" :)
I know about the frame drops. Unfortunately, unnecessary operations also run that it would be good to skip or run in a different order. I consider this a disadvantage of programs coded in basic. It's easy, but it has its drawbacks... and we work with what we know and what we have.
