Does anyone know how I can get information on the .gcm file extension of which Dolphin Emu opens. I have tried Google for about 4 or 5 days straight and there is nothing on the net. I have also tried MSN and a few P2P Apps. I know how to open them up and view there data, but I would like to know some specifications on the encoding data structure of the .gcm. I have realized it is almost like an .iso image, but there are no special programs that make these that I can find. I am working on a "Tool" right now for these files, and do not want to go through all the trouble of doing it myself, when someone else may have already done this. Please get back with me on this. :happy:
