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.

Changes:

Holger Eilts has improved the menu layout quite a lot
Loading separate files in a .D64 from the menu is now possible (Holger Eilts)
It’s possible to store and load files in subdirectories now
By pressing F10 while in a network game, you can type in a message to the other player with the USB keyboard
Sound cracks are now gone (thanks to Tantrics new SDL work)
