Crash dump files
 

Toni, I've managed to get WinUAE 2.5.0 to crash several times under Windows Vista. Vista creates a ~70MB crash dump for each crash. Are the crash dump files any use to you? (I don't think WinUAE created its own minidump file in this case.)

They should be useful, unless crash is caused by something external.

Crash dumps are normally created by winuae (Check if it contains complete winuaebootlog.txt) Dump files should compress really well. Try also lowering Amiga side memory size, it should decrease size of dumps.
