Virtual CoCo is a PPC native demo application.

The "autotyper utility" that had been that had been donated to this page has been removed, because it was reportedly contaminated with a virus. Rest assured that all of the other files (which I personally made) available via this page are clean.

Virtual CoCo 0.9.5 is now available for download, sporting:

cleaned up sound
enhanced disk interface
preliminary printing support
enhanced keyboard support
faster tape loading
assorted bug fixes (mostly video-related)
a non-modal debugger

Known problems:

video is reportedly still slower (than in v0.8) for some users, unfortunately
the BREAK key and SHIFT+@ are not currently handled
the PLAY command has a glitch between octaves 2 and 3 (most likely a 6809 bug)
interrupt handling is not 100% accurate
timing problems in some games (i.e. Rail Runner)
LLIST does not output newlines to printer.out
the Mac cursor should be made invisible when over the CoCo window
tape writing and saving is temporarily disabled
the file type for .CAS, .DSK, and .PAK files must be manually set (see the documentation)

Make sure to read the accompanying README file before sending me any questions.
