GCM is a command-line tool for manipulating Gamecube game image files. It can display information such as the game ID, region, maker ID, and filesystem, calculate the CRC32 checksum, and shrink the image size, similar to GCMUtility Wii.
Usage
From a command prompt: * gcm [-fs|-sh|-crc] <filename> : -fs: Display the filesystem of the image. : -sh: Shrink the image. : -crc: calculate the CRC32 of the image.
Requirements
Archive contains Windows exe and C source code. The source code can be compiled for Linux and Mac.
Compatibility
- Gamecube ISO files work just fine.
- Since Wii ISOs have a similar format, it can get some information from those as well (game and maker codes, region, game name). Do not use the -fs nor -sh options on Wii images.
- Shrinking compatibility
- It has been discovered that some games are shrunk differently with GCMUtility Wii. This has caused some instability in the images created with this utility. Listed are ones that have become known to have issues while shrunk:
- Super Monkey Ball - Freezes after the first couple intro screens.
