This is libgcm V0.1a, an early alpha of my library for manipulating gamecube master files. It currently has little functionality, but you can list and extract the contents of GCMs - the only thing I haven't got extracting correctly yet is the apploader stuff, because I haven't even really begun working on that yet, and don't know how to really test the results of that extraction. Before this is over, I intend to have the library ready to insert, append, and create entire new images for burning to a GCM. My final test of this ability will be to completely unpack a disc image onto the drive (which it can already do, with the exception of the apploader) and re-pack it and see if it plays. Maybe someone will be helped by this code. GPL applies. This code is free as in freedom. If you have any additions you would like to see in the next release, I'd be happy to include them, with credit. Just email them to me or find me in #gcdev on EFNet. Enjoy!
