Are there any information on running the same OSes supported by SheepShaver on QEMU?

I am trying to find more information, but is really tricky to get proper results on any QEMU-related topics.

I think maybe it could be more stable than SheepShaver to the point we can use, say, Office 2001 or things like that.

Hi,

There used to be the GSOC project aimed at booting OS 9 with Qemu, but it never delivered. You can search the forum for info.
Qemu currently only boots 10.2 to 10.4 successfully, but runs them rather slow.
Actually your best bet for running Office 2001 somewhat stable is by running it inside wineskin on OSX ;-)

Best,
Cat_7

There's been some halfhearted poking at that GSOC project, and some of the changes that were needed for OS X emulation made it back into the trunk of qemu and openbios, but without a strong push, the other hardware support is not likely to make it in there. The current code mostly came from Mac-on-Linux and Mac-on-Mac IIUC. Qemu is going to come up against the same MMU etc. issues that SheepShaver, PearPC, et al have hit; and once someone's solved those issues, the method should be equally available to all projects (since the licenses are all similar).

Oh yes.. office crashes because of memory issues, yeah?
Can't the QEMU emulation be done without MMU, though? Even to pair with SheepShaver, it would be nice.

By the way, I found this nice text by Natalia Portillo on Macintosh emulation, worth reading:

https://lists.gnu.org/archive/html/qemu ... 02378.html

Sadly, it feels like we are far from having proper emulation. =(

I am going to dig deeper into low-level C programming and play a bit with some simpler emulators and lets see if I can contribute in the next few years. =P
