Frodo- is a Commodore 64 home computer emulator. It was ported from Christian Bauer's original Frodo for Amiga. Porting for Epoc was done by Jal Panvel and Alfred E. Heggestad. Porting to Nokia 9210 and S60 was done by Hannu Viitala. Frodo was released for 9210 on July, 2001. That was the first C64 emulator for any mobile phone.
