Aion ported the well known C64 emulator Frodo. His port is based on previous Wiz and GP2x Frodo ports.

Release notes:

* Slightly change of default control map to be more compatible with GPH Platform Development Guide button description:
I – Menu;
II – Virtual Keyboard;
Home – Quit(immediately);
Pause – Pause;
* Preferences now saving on(and loading from) SD Card. Known issue – it doesn’t save the current selected control map, so it will be set at default on the next start.
+ Added pause mode with switching backlight intensity. (Remember, it doesn’t restore backlight intensity as it set in firmware preferences(because i don’t know how to obtain this value), it will be restored at 75% of maximum brightness).
