A low level Commodore 64 emulator written in Actionscript 3



FC64 is a low level Commodore 64 emulator written in Actionscript 3.

It is licensed under the GNU General Public License. See the LICENSE file for more information.


  • libfc64 - Core library project (.swc) that includes the FC64 emulator and two display-list classes to make the emulator easy to use in other projects (FC64Sprite for Flash/ActionScript projects, FC64UIComponent for Flex projects).

  • fc64shell - Sample Flex project showcasing FC64 usage with some sample public domain ROMs to load and interact with.

  • fc64-android - AIR for Android project that allows FC64 to be packaged as an .apk to be run on Android devices with the AIR runtime installed.


The FLEX_HOME environment variable must be set, and must point to a Flex SDK that includes the AIR 2.5 SDK.

To compile and install the Android application, a few things need to happen:

  1. Build the libfc64.swc file. There is no build script for this, but you can import this as a Library project into FlashBuilder to get a .swc file.
  2. Make sure the AIR Runtime is installed on your phone.
  3. Connect your phone to your computer
  4. Make sure you have a certificate available for code signing, and update the file with both the path to the certificate and the password.
  5. Navigate to the fc64-android directory and execute the following: ant -f ./build/build.xml

The default target will compile the code, package the .apk file, and install it on your device.
