The ver.req trick works on this camera. To retrieve the version information, create a new blank file called ver.req on the root of an sd card. Insert the card in the camera.

Porting process & links[]

In November 2009, revivery released a first version of CHDK for the S80 for testing purposes:

This testing release is compatible to firmware version GM1.00G - see above for the firmware image and update procedure. Many features are working, but more testing and development is required.

Note, that once a SD card with write lock and a modified bootsector is inside the camera, the only way to switch the camera on is by opening the lense cover or holding the play button for more than 2 seconds.
