|  cc65/Plus4 programs and IRQs?
Uhh...this is probably a stupid question, but I'm working on a few programs for the Plus4 using cc65 and suspect improper handling of IRQs to be why they don't work. I want to disable cc65's alternate IRQ handler except enough to delegate it directly to the ROM routine and switch RAM back in when done. How do I do that? BTW, I'm willing to post one of the problem programs' crt0.s file if wanted. |
