2025-12-29: I have restored the wiki to a backup from the end of November. Starting in September 2025, accesses went form the 800MB-1.2GB range per month to 26GB in September, 42GB in October, and 70GB in November with most accesses originating from China. As soon as I realized what was causing all the access problems in November, I shut it down (it had reached 36GB by then) behind a password/login screen. The database had gotten corrupted, and I tried a restore from just before the spike in access but that didn't work. Thus, end of November. I still have the other daily backups so if there were any important additions in December, let me know and maybe they can be recovered. - Allen H.

The VCC Emulator (Originally called "Bjork") is one of the most versatile Windows Based Emulators out there rivaled only by M.E.S.S (Multiple Emulator System). Current version (as of May 2015) is 1.43beta, released on April 2013.

Description
VCC is a small (under 1 MiB) modular Color Computer 3 emulator. The installer includes all that is needed to run the program, and it can be used as a portable application without needing any modification, making possible the concept of "CoCo in a pocket".
Version 1.42 can emulate a CoCo 3 with 6809 or 6309 CPU (overclocking up to 89.4 MHz), 128, 512, 2048 or 8196 KiB of RAM, 2 Joysticks, 4 Floppy Disk Drives with the FD-502 controller, 1 Hard Drive with Cloud9 controller (with real time clock), MPI and Orchestra-90 CC.
It can simulate RGB and composite video output in windows or full screen.
History
VCC was initially created under the name of "Poco", latter changed to "Bjork" as an homage to Steve Bjork, reaching version 7.35, and finally changing to "VCC" in June 2007, resetting the version count to 1.0.
