Hi !
Following a discussion started here

One more thing... is there any way to have the camera always start in record mode when pressing the ON/OFF button? It's annoying to have to hold the button down. Is this standard behavior for CHDK?
i prepared a small patch to allow changing the button behaviour:
patch adds 'OPT_REVERSE_BOOTLOGIC=1' to buildconf.inc -> binary will show 'reversed' boot behaviour:
- short press on either on/off or play button starts cam in shoot mode
- long press play button starts cam in play mode
if you change the buildconf.inc entry to '#OPT_REVERSE_BOOTLOGIC=1' -> binary will show normal boot behaviour:
- short press on either on/off or play button starts cam in play/review mode
- long press on/off button starts cam shoot mode
tested on ixus870_sd880, should work on: a2000, ixus870_sd880, ixus980_sd990, sx1, sx10, sx100is, sx110is, and sx200is
Caveats/remarks:
- this will not make your cam start up any faster (at least not much)
- this will increase the chance of it accidentally extending the lens ...
- patch is against r820, works on r822 as well
hoping this 'paparazzo' mode is more usefull for others than it is for me
