Firmware information
Per the CHDK FAQ 1.3
Power on in PLAY mode with ver.req file on SD card, press and hold FUNCSET, press ZOOM OUT to reveal the firmware version. For example:
Canon PowerShot A470 P-ID:317A NT D Firmware Ver GM1.01B NoError Feb 12 2008 21:18:24
A subsequent press of ZOOM OUT (while still holding FUNCSET) reveals (for example):
Adj Ver.010.004
If you power on in PLAY mode without ver.req on the SD card and press the FUNCSET and ZOOM OUT buttons simultaneously, the screen shows:
Firmware Ver. 1.0.1.0
[ OK ]
Subsequent presses of ZOOM OUT have no effect. One must press FUNCSET to clear the screen (i.e. answer the OK).
Using the filename vers.req with the above sequence will replace the IS Firm version output with the total number of shots taken by the camera to date.
Language Interface
Set mode switch to PLAYBACK. Hold down FUNCSET and press MENU, this will brings up a menu where you can change the language interface for the camera. Use the direction button to select the language and press FUNCSET to accept the selection.
Other button sequences don't seem to do anything.
