I’m happy to finally be able to let the cat out of the bag. Darron Schall and myself have been working on a low level 6502/6510 emulator and, based on that, on a Commodore C64 emulator/simulator.

The emulator is completely written in Actionscript 3 and runs on Flash Player 9. It loads the original binary C64 Kernel ROMs at runtime, and executes them just like the original hardware would do.

The sources are released under GPL, get them here:
