There are some new Mini vMac versions available!
http://minivmac.sourceforge.net/
Version 3.1.3 is now officially released, and there is a new alpha with the version number 3.2.0. This one is focused on the Mac II emulation which is "so much improved since 3.1.3."
There are some compiled versions of the alpha available here:
I built a Macintosh II version and color isn't really stable (it crashes alot). Just don't enable color under 3.1.3 (I don't know if it's fixed in 3.2.0 ).
Well, the author does say that the Mac II emulation is "so much improved since 3.1.3." So I reckon that maybe some of those crashes have been worked on.
Thanks for the update about the new version of minivmac.
FWIW, your statement about Macintosh II emulation came across as if Mac II was ready for use... the Mac II emulation in 3.1.3 is officially described as follows (bold and italics formatting is my work, original text is not bold italic):
"Mini vMac 3.1.3 is now officially released (with no change from the final beta, as usual). Mini vMac 3.1.3 is rather old news by now, which is how it should be. There should be no surprises in the stable version. The Changes file lists what has changed since Mini vMac 3.0.4. To summarize, the main work has been on Macintosh II emulation, which is not yet complete, but also the default Macintosh Plus emulation is a bit faster and smoother. One fun new feature is a compile time option to emulate a hacked Macintosh Plus with larger screen sizes.".
From the authors website, I get the feeling that Mac II emulation is not 100%.
