Would it be easy for anyone to make it possible or if i could used the 101c version without implications?
You can try the 101c version. It might work at least partially as the version numbers are only 1 release apart.
Edit: I'm not sure if the version check on boot is implemented for this port. If it is, then it will not boot on your camera. Sorry for the confusion.
But if you will dump the firmware from your camera, save to any file sharing site, and post a link here, we can tell you exactly if it will work or not. A firmware dump is also meeded for making a CHDK version for the 1.01d version in the event that becomes necessary.
Instructions for obtaining a firmware dump can be found at this link :
