Talk:IRQ

Is it really impossible to acknownledge a DMC IRQ by reading $4015 ? It's weird this register has a DMC IRQ flag, but that reading it would not ack the interrupt. Also it sounds fishy you'd have to stop the sample and restart another one to acknownledge.Bregalad 14:00, 24 April 2012 (PDT)

Table

Just how comprehensive do we want this list to be? Obviously including every single mapper with IRQs is overkill (q.v. my list, sort it by IRQ presence), but does it make sense to include non-US mappers here? If so, why these ones? (e.g. there were more games released on the Namco 163 (20) than the VRC4+6+7 combined (16)) —Lidnariq (talk) 18:28, 17 May 2015 (MDT)

Yeah, actually the whole table is probably useless. Knowing some value to enable/disable/ack an IRQ is too little information to do anything useful with it (except the disable, I guess). Really that information is best left at the article page. What we really need is Category:Mappers with IRQ, and your list is a great TODO list for building that category. I guess this article needs a rewrite with a better focus, probably. - Rainwarrior (talk) 18:50, 17 May 2015 (MDT)
