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:
Fixed a truly embarassing bug with the HOME button on the wiimote. Unfortunately,
… It no longer links with Yohanes SDL version, which for some reason broke the menu code with the wiimote (but not the classic controller!). It’s probably unrelated but I can’t have it like that. Further investigation pending.
