Well complete system emulation is very very slow, which is what I have used in qemu. I had forgotten it did the instruction emulation only as well. > I'm not talking about using QEMU as a system emulator, just an > instruction set emulator.

OK, using the instruction emulation, then you could do that. That's a pretty good idea. I will have to play with that some more some time. -- Len Sorensen -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
