Can somebody point me to articles regarding the use of interrup handlers on konami megarom games?
I am just dissasembling the roms of those games and i would really like to learn more about the use of interrupt handlers
What i know is that z80 works in im1.There is a bios routine at 38h.From what i read in the msx reference manual that has a disassembly of the bios,It reads the vdp status,scans and read the keyboard,psg handling and music and etc.
Now i have a question regarding the use in those games.I suppose they reject the default 38h call with a custom one,and maybe put the status of z80 from im1 to im2 ?Isn't im2 the only way to have your custom interrupt handler to any memory address the programer wants?
Did konami ever used im2 in their games?Or they do something else?
