VirtualC64 v4.4 is released. VirtualC64 is a C64 emulator for Mac OS X from Dirk W. Hoffmann. VirtualC64 emulates a Commodore 64 personal computer on your Macintosh.

VirtualC64 v4.4 Changelog:
Added support for VC1451C drives.
Added support for Dolphin DOS 3.
Added more Drive ROM fingerprints.
Drive configuration has been simplified by adding an auto-config option.
Now the CPU load of the emulator thread is measured and displayed in the status bar.
The internal thread management has been reworked from ground up.
The speed of the C64 is customizable now. Besides a "native" option that lets the C64 run at its original speed, there are two slow motion modes and two overdrive modes. The first two let VICII output the video signal at 25Hz and 30Hz respectively. The latter two output the video signal at 100Hz or 120Hz. There are also true 50Hz and true 60Hz modes that allow smooth output on 50Hz monitors or 60Hz TFTs.
