    I know of a program called GCM fixer or something in that order.
    It was used to fix GCM games to ISO for burning on mini DVD.

    Is gcz really an other file format or only an extension?
    You can try "wit dump my.gcz" ("wit" is a command line tool, see my signature) to get an analyze of the file.

    Yeah first guess here too :P
    @OP:
    Try to open the file with 7zip, maybe it's just a compressed GCM file. If it is one you can just extract it and rename to ISO.

    GCZ is a FILE FORMAT .. Is a internal compressor of DOLPHIN EMULATOR.
    If you press right click on iso list u can compress iso file to GCZ format.

    here a source http://code.google.com/p/dolphin-emu/source/browse/Source/Core/DiscIO/Src/CompressedBlob.cpp

    but i need to decompress this kind of file for have a normale GCM file for use that in normal mode (swiss,or burn iso (after gcmtoiso)

    Are you able to use this dolphin version?

    Maybe you have luck :P
    Why the hell do they even use their own compression and no regular one lol.

    I have yet only found the source code. If I have some technical info I could try to support it in my tools.
