There is a new snapshot of Mini vMac available today:http://minivmac.sourceforge.net/
"The latest Development source snapshot continues to improve the X version. To match the behavior of the Macintosh and Microsoft Windows versions, it now tries to determine the application path. This is used when looking for the ROM image, and in looking for disk images named disk1.dsk, etc. If the application directory can not be determined, it uses the current directory, as before (which is often, but not always, the application directory). The application path is also used to determine the application name, which is displayed in the window title bar. (If the application name can not be determined, "Mini vMac" is used as before.)
Determining the application path is implemented (in somewhat different fashions) for Linux, FreeBSD, NetBSD, Dragonfly BSD, and OpenIndiana. I've not figured out an implementation for OpenBSD and Minix.
The build system now supports compiling 64 bit versions for OpenBSD (-t ob64), NetBSD (-t nb64), Dragonfly BSD (-t db64), and OpenIndiana (-t oi64).
Mike Fort sent a fix in setting up the ethernet port in the LocalTalk emulation. And I've put in a considerable amount of debug logging code into the SCC emulation (enabled by preprocessor condition), to make it easier to figure out what it is doing. "
