Hi all,
been reading the forums quite a lot recently as I have been delving into the realms of nes emulation.
long story short:
I'm receiving this error:
FAIL OP : $28
Unknown Error
$F93C
$28 is PLP
I noticed the 16bit value changes when I execute more/less cycles in the instruction (the shown value is for 4 cycles)
My emu is based off bisqwit's amazing 900line emu, i had attempted nes emu development multiple times before but without much experience and knowledge I always got stuck, best I reached was SMB intro shown badly (tiles and colors messed up) but bisqwit's opened my eyes to accurate emulation ( 3 ppus & 1 apu each cpu cycle, properly placing tick functions in the opcodes that execute those ppu and apu cycles )
if anyone can point me to which part of the cpu i should be fixing i'd appreciate it.
