When using multiple memory cards do we have to install the hack each time? Also, if the firmware is already loaded on the camera, do we still need to have the firmware loaded (separately?) on each memory card? I just purchased a new memory card, am going to format it on the GH1 and am wondering if I have to do anything to use the GH1 hack as I already have the hacked firmware loaded on my camera. Sorry if this question is obvious, I'm still learning :)
