WinUAE-Debuuger: Memwatchpoint and AUTOCONFIG

[selco]

Hi Toni,
while trying to look closer into the Autoconfig mechanism I tried to set a memwatch point to catch access to the ZorroII Autoconfig area.

That does not work, the access does not stop the emulation.
(I have 1 MByte Z2 Fast Mem configured)
The memwatchpoint even makes this fastmem diasppear! Removing the watchpoint make the extra mem re-appear again.

Here is what I did:

WinUAE 3.0.0 (2114.12.17) Jit off, cycle exact, A1200 3.1 ROM

New Start

Possibly fixed in next beta. It isn't really designed to work with memory "banks" that move around.

Just tested with WinUAE 3.1.0 Beta 12.
-> Works!

Thanks Toni, its very much appreciated!

Best regards Alexander
