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.
