EDIT: don't bother, I found my bug, IRQ are working as expected, it was due to some buffer overlapping (hard one!) ;)
Hi,
I'm currently having some problems while streaming data from the arm9 to the arm7, and the only problem I can think of is a problem with nesting interrupts, as my streaming method is really simplistic, and I tried 3 differents, with the same results..
So here are my questions:
-if I enter in my VBL IRQ handler, but it's taking a long time (more than 1vbl) so another VBL occurs, what happens? does it reenter into the handler or is masques, or even queued for later call?
thanks, I'm really scratching my hair on that problem...
