Hello & welcome, kimgkimg !
I see that there were ports for the v101a and v101b versions and the firmware for v101c was dumped a while ago. Was there ever a port done for the v101c?
AFAIK not.
Where's the 101c dump ?
Have you tried the existing CHDK versions on your 1.01C camera ?
There's also a 1.05a firmware out there which works well with one of these CHDK versions...
