Hannu Viitala has been developing Symbian OS ports of Frodo, Commodore 64 emulator, since 2001 or so. This time he has released a S60 3rd Edition version. Now you can enjoy all those great C64 games directly on your mobile phone. If you like the emulator, consider donating some money to the author; in exchange you will receive from him a library enabling sound in the emulator, which is not supported in the free version.
