Hi there!
When giving Gunfight its final touches, I stumbled
across some very severe bug in PCAE, which I think
everybody developing on this emulator should be aware
about:
There's a bug with SBC $$$$,X.
It is changing the ROM contents!
For example this simple loop:
LDX #$00
NextByte
SBC $F000,X
DEX
BPL NextByte
Would not only change the accumulator as intended, but
completely overwrite all F0XX bytes too!
There might occure other errors with other indirect
addressing opcodes as well, I didn't test them all.
(Just the one ruining Gunfight :-))
Greetings,
Manuel
