SheepShaver Windows + JIT + Newworld + Mac OS 9

Wed Mar 11, 2020 2:32 am

I'm chasing a crash on boot of SheepShaver on Windows in JIT mode with Mac OS 9 and Newworld ROMs, and I've figured out goes all the way back to Jul 16, 2006 (git revision e07e2196). Given that this crash has been around for so long, I'm curious: is there some combination of SheepShaver settings or ROM version or other workaround that anyone knows of for using SS w/ Mac OS 9 + JIT + some newworld ROM that doesn't crash on boot on Windows? Or do people just always use Oldworld ROMs for Mac OS 9 on Windows (or else not use JIT)?

If you search for "MacOS9 for Windows" you'll get to my standalone system, which uses a build dated February 2017. The web page says it uses a build made by Ronald, but I'm fairly sure that's a mistake. I think I built it with your code at the time, but with JIT disabled in the code itself. The prefs file in the system has JIT true, but of course that won't mean anything if JIT was disabled in the code itself.

I'll try to find the build environment that I used, but I haven't been able to locate it so far.

In answer to your question: I don't think anyone ever sorted out NewWorld+JIT on Windows. They just used the OldWorld ROM as a workaround.

Indeed, I never built for Windows.

I think I must have lifted that sentence from my page about the macOS version of the system; apologies!
