New Mini vMac Alpha: March 1, 2014

Post by ClockWise »

Work on the 3.4.x branch of Mini vMac has begun:

http://minivmac.sourceforge.net/

There is an alpha version now available. The main site says:

"The specific changes in 3.4, version 140226 are:

The Windows version wouldn't compile with magnification disabled (-mf 1) and screen depth (-depth) of thousands, millions, or 4 colors. (It's not clear to me why disabling magnification is a popular request.)

The Classic Mac versions ("-t m68k" and "-t mppc") didn't always request a large enough memory allocation in the SIZE resource, particulary for large screen sizes and color depths. The build system now tries to compute the memory requirements more exactly.

The hack allowing the emulated Mac Plus (and other models without Color Quickdraw) to have a larger screen always allocated enough memory for a screen with up to 1048576 pixels. It now allocates more closely to just the memory needed, and can handle screens up to 2097152 pixels (the size of the unused area in the address space that is used by this hack). I believe the previous limitation was mostly consequence of how earlier versions handled memory access in the CPU emulator. The build system will now give an error when the requested screen size contains more than 2097152 pixels (before it would compile fine and just not work right)."
