Not sure if this means I can ignore the setting for now. @waterwingz?
I'm not sure which cameras won't override with something in the hot shoe and which will.  One of the comments in the threads I posted suggested that it may depend on the camera shooting mode ( P, M, AUTO, continuous, etc ) as to whether it's an issue or not. Mostly a question of whether the code takes a different path through one of the hacked tasks when the sensor detects something I presume.

There was another reason for being able to override the hot shoe switch posted.  Pretty weak but it was to allow cameras with broken (or sticky) sense switches to still work normally and ignore the hot shoe when shooting normally in Canon mode.

Note : as reyalp reminded me yesterday, stubs_entry.S has the necessary definitions (even for D6 cameras like the sx60 and g16)
Code: [Select]
sx60hs/sub/100c/stubs_entry.S://#define HOTSHOE_FLAG        0x00000800 // Found @0xfc5cfbcc, levent 0x204
sx60hs/sub/100c/stubs_entry.S://#define HOTSHOE_IDX         1
Ported : A1200  SD940  G10  Powershot N  G16*

Yes.  The index should be 1 not 2.  I thought I had blindly copied those from another port.  So the excersise to log keys was a good refresher for me but unnecessary..
I'll put it in the port for now.

Hi, there seems to be a problem if the long exposure is set to more than 3 minutes. The camera will stuck, if I press the shutter button again, it will say interrupted, but other buttons do not work (including power and alt). I have to remove the battery to reset it.

Thank you so much for helping find problems! Can you please tell us your firmware version. I have not tested 3 minute exposure (yet).

Do you have dark frame subtraction disabled? If not, the camera will likely be unresponsive for 3 minutes following the initial exposure.
Don't forget what the H stands for.

Hi, thanks for the fast reply, my camera firmware is 100b, I did not check if the dark frame subtraction is enabled/disabled, where can I find this option? The behavior is after I press the shutter, and press it immediately after, this usually interrupt the script and return to normal shooting mode. but if I set the long exposure for more than 3 minutes, after I press the shutter button, the display will go dark and nothing I press will affect it, not shutter, not ALT, not power, The only option I find working is to remove the battery.

Dark frame acquisition will typically happen for most exposures over 1second by default. ( the camera will take an exposure with the lens shutter closed for an equal length of time in order to measure and subtract noise from the original long exposure)  During this time the camera will seem unresponsive.  I've been fooled into thinking there's a bug by this as well. 
Check that "Darkframe subtraction" is set to off in the CHDK menu "Enhanced Photo Operations menu". 
Or try waiting an additional 3 minutes for dark frame acquisition and subtraction ;)
