Quoting Colin Piggot <[EMAIL PROTECTED]>:
Interrupts aren't affected by the speed of the machine.The ASIC generates the frame interrupt every 50th of a second, it's all tied right into the video timings. So things like music players, or any frame interrupt (or line interrupt) routines don't need to be changed at all.
I guess you could do much more in between the interrupts however :-)
