Frodo is a Commodore 64 emulator written by Christian Bauer ( http://frodo.cebix.net ). It was ported to the Wii by Simon Kagstrom and does not share any code with FrodoWii.

Put .t64 or .d64 files in /apps/frodo/images on your SD card. The in-game menu allows you to insert disks/tapes, load them and configure the display, joystick ports etc. Saves will be stored on the SD card and the preferences are stored persistently. Wiimote 1 is by default the joystick in port 1 and wiimote 2 the joystick in port 2, but you can swap this.

Holger Eilts has made a version with better menu layout, alternative USB keyboard support, screenshots and the ability to load files within D64s directly. This release tree is known as “Frodo Comfort”. It’s based on Frodo v8 and therefore does not have network support.
