Subject: Re: [stella] Severe Bug in PCAE discovered... From: Dan Iacovelli <Dan-AVC@xxxxxxx> Date: Mon, 19 Nov 2001 19:46:03 -0600 |
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
is this with pcaewin or the dos version? I use the windows version mostly. Dan Iacovelli
