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.

It has only been tested in 480i mode on a PAL TV (the 50Hz mode gives me a headache). Sound support is slightly buggy, but usable. The emulation is not perfect, so all games will not run under Frodo. If you have multiple versions of a game, try each of them as often at least one will work.

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.

Changes:

Emulation speed has improved a bit
Keybindings have been improved and extended (commodore key, del etc) and now behave more like the real keyboard
Added support for the classic controller. Note: this is untested since I don’t have a classic controller. Please test and fix bugs in this part!
Add support for loading .prg, .p00 and .s00 files. Only .prg has been tested so the others might not work.
Various glitches and small bugs (long filenames, sound in menus, frequent prefs saves etc) have been fixed
