Memwatch functions in Action Replay III don't work in WinUAE

Galahad/FLT · 18 February 2013, 02:22

As per the topic, when testing this today, Action Replay just didn't activate at all even though I could go back into AR and see that an address had changed.

Any idea Toni?

It probably needs some AR hardware support that is not emulated.

Better use UAE debugger memwatch points, they are more accurate and completely undetectable.

(w-command)

Or it was changed via a blit, in which case you won't detect it!

System friendly no blitter usage

Any chance this will be looked at in the future?

Why can't you just use the w command for now? It will surely do exactly what you need and not require more hacks to WinUAE!

Firstly i've never used WinUAE debugger, and secondly, adding functionality to all supported peripherals is when considered a hack?

Well you can learn something new by hitting Shift-F12 and type "h" to get the help screen (or read the docs) and use the functionality already in WinUAE now, or wait days/weeks/months/years for a feature that may be difficult to add!

Seems a pretty simple choice to me...

I did quick debugging.

AR3 memwatch points only work if program does not use STOP instruction (=mainly programs that take over the system). Memwatch points use 68000 trace mode (sloowww....) and STOP resets trace bit.

(Real A500 + AR3 confirmed)

Thanks for lookin Toni

Guess it would slow the emulation down too much to include it.

Toni Wilen · 22 February 2013, 14:47

I meant using AR3's memwatch will slow down running program greatly (at least 20 times slower than normally) due to active trace mode. AR3 mematch is a software trick. (Disassemble 68000 trace exception vector address when it is active..)

AR3 memwatch works in emulation, just like on real hardware = nothing happens if AmigaOS is running.

I was interesting in ripping any sounds and graphics. Is it possible to do it using this AR3 rom? I'm using WINUAE.
Any help please?
Thanks in advance.

Ripping sounds (if you mean samples, not music data) probably is easiest with winuae built-in sample ripper. Check other threads.
