VirtualC64 v0.9.5.1 for Intel Macintosh OSx

VirtualC64 emulates a Commodore 64 personal computer on your Intel Macintosh OSx > 10.6.

I wrote the software with two major goals in mind. First, I wanted to create an emulator that can be used as a demonstrator program in a first year or second year course on computer engineering.

To achieve this goal, I have integrated various debugging capabilities that let you peek inside the CPU, RAM, ROM, or one of the custom chips. Second, I tried to make the emulator as user friendly as it can get.

In short: VirtualC64 tries to combine the ongoing fascination of the ancient Commodore computers with the great user experience of today’s Macs.

Bug fixes and enhancements:

  • Fixed a bug that caused the emulator to crash on startup on some machines.
  • VirtualC64 supports OS X Lion.
  • Preference panels are now tight to their individual virtual machines.
  • CIA debug panel has been redesigned.
  • Deprecated CoreAudio API calls have been removed.
  • Fixed a bug in the BCD to binary conversion routine.
  • Fixed a bug that caused the TOD to wake up too early after reading the tenth of a second register.
  • Thumbnail images are now rendered properly when switching from PAL to NTSC and vice versa (issue #107)
  • Fixed a bug that caused keyboard events to be rejected when the main window got focus (issue #110)
  • Fixed a bug that caused a discolored line to appear at the right border of the screen texture.
  • Yet another startup animation.
