Hello,

i have a simple question.
can i write to the blitterregister, while it is working?
i want to write it because, i save time. if the blitter is prefetching the register,
i can. but is it?

short: no.

long: according to Toni Wilen, any write to blitter registers while it is working, will make it crash.
