- I think that if you examine how UAE's 680x0 emulator works you'll find
- that it's probably on the order of five to ten times slower than
- Executor's Syn68k.

- There are NO other Mac emulators for the PC. There is no hint that
- anyone will be doing it better soon. You don't understand the issues
- involved. Read ftp://ftp.ardi.com/pub/SynPaper for a description of
- the dynamic recompilation technology Executor currently uses. We
- already have a successor to Syn68k partially written. Furthermore,
- even if you used Syn68k itself to emulate the ROMs you'd have
- ridiculously slow performance because the OS and toolbox routines
- would then be emulated -- under Executor they're all running native.

- It doesn't work that way. UAE's m68k emulator would have to be
- rewritten from scratch to get the preformance that Syn68k does.
- Apple's ROMs would have to be rewritten from scratch (which is what
- we've done, which is why it's taken us 10 years to get where we are)
- to get the performance Executor gets. If you're rewriting all of that
-
