TODO:
Fix this arrangement (specific for Bonk's Adventure)!
pre-deprecat lib note says:
Even though 3 interrupts are triggered, I set an int_num of 4. (notice '+1')
I agree that it is kind of a misuse of the function, but I haven't found
clues in code on how interrupts are scheduled...
IT5 is the main int, and needs more time to execute than IT 3 and 4.
Between other things, each of these 2 int are responsible of translating
a part of sprite buffer from work ram to sprite ram.
So now test mode is fully working and visible.
