NMIB / IRQB timing (applies to NES as well)

Don't want to copy / paste the whole thread, the question is posted here:

I was hoping someone from NESdev might have come across this timing issue on the NES hardware as well, since they're so similar -- especially regarding NMIs, their delays, the two-stage pipeline, etc etc.
If you have any thoughts, you can respond here or on the Zboard, I'll check both.
Thanks in advance!
EDIT: nevermind, figured it out. See the above link if you care, and thanks again to dvdmth for assistance.
