RawTools, NMM2GCI 0.3, ZeldaTPConverter and ctr-gcs_0.3b
Since google code is closing, I'm keeping these files here.
RawTools: This package contains a set of tools for tweaking memory card raw images. Please refer to each tool's readme file for more specific information. Contains GCHeader, GCSerial, GCPadder and mci2raw.
NMM2GCI 0.3: This tool converts to and from gci files and "no more memory" gamecube memory card savegame format.
ZeldaTPConverter: this tool converts a "The Legend of Zelda: Twilight Princess" savegame from gamecube format to wii format and vice versa.
ctr-gcs_0.3b: a memory card management tool like GCMM, but use GCMM since it has more features and more testing behind it.
