Interrupts in com files
Posted: 31 Jul 2022 05:58
I'd like to move from using run files to com files, so I can have access to more memory for some of my games.
When I moved to the com format, interrupt stop being run.
I've been setting 0xfa98 to jp my_isr, which works well. But when I moved to using .com files, it doesn't work.
I've also tried setting 0x38 to jp my_isr, but that isn't being run either. I've check the memory address, and it's been set correctly. Interrupts are enabled.
Normally I would run it in mame and check, but I don't know how to load and run com files into mame.
Any suggestions?
