Hi,
I've just compiled qemu 0.12.2 for Windows under msys.

I am using "-m prep -M 750" options which on 0.11 worked fine. In 012.2
however, I get the following error:

This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information.

Am I correct, that somehow the CPU was recognized as PowerPC 601 / 620 /
970? Is this OK?

Any help greatly appreciated.

Nope this is not correct.

And I don't even see why the 601 / 620 / 970 are treated as equal.

You are asking to run a fully implemented "so called G3" PowerPC  
processor.
However the 601 is a hybrid PowerPC/POWER ("G1"), the 620 is a 64-bit  
early implementation ("64bit G2") and the 970 the final 64-bit so  
called G5.

There is no relation at all between that four CPUs.

I guess you mean -cpu 750?

So the only thing I can tell you for sure is that the prep target is  
pretty much unsupported. I'm trying to keep the newworld bits  
together, but prep is really missing a maintainer.

What that means is that you're pretty much on your own. Patches are  
always welcome though. So if you find the reason it doesn't work, feel  
free to send a patch!
