My Zelda project has hit a snag once again, and this one I can't figure out.

I've had guidance in my custom asm from members at nesdev, in how to get a custom mmc5 irq to fire up.

So within the latest fceux emulator, my irqs work/display correctly.

But just as I was about to release the first beta, it was discovered that my custom irqs don't fire up in the emulators nintendulator and nestopia.

What's even more bizzare, is one of my screens that is supposed to have an irq, won't fire up as mentioned in nintendulator, but, if I open the debug menu, and goto the irq section, and toggle on/off any if the 4 boxes, my irq displays in nintendulator.

I'm at the end of my rope. I've lost almost a week just on this issue alone.

Is there anyone here that could shed light on this, or even lend a hand in fixing this?

Thanks for reading.

edit
Go figure, I post for help, and then I figure it out. Turns out I need to have $5203 constantly written to within the NMI. I have my writes within the irq's themselves.

If a moderator could either please lock or remove this thread, I'd appreciate it. Sorry for the waste of space, lol.

It always happens like that. Always. Whenever I struggle with a problem, and then make a thread about it, I always figure it out once I have made the thread. It's crazy. But it always winds up being the case.

I'm glad you figured out the problem.
