Herein lie dumps of aftermarket ROM upgrades for Commodore gear that I personally own. I am making these available so that they remain available to Commodore enthusiasts.

These images will NOT work in emulators. To make use of these images, you will need an EPROM burner, a switch and pullup resistor (where noted), and common sense.
