Utility description

GameHeader is for decoding and displaying the "registration data" section of a rom file. For a game to be granted a license, Nintendo required that publishers write informational values in a reserved area of the rom. This process started with the SNES, which is why NES emulators can't derive memory mapping from the ROM.

You need .NET Framework v2.0 or higher for the tool.

This utility reads headers for:

*SNES
*NDS
*N64
*NES
*GBA
*GB
*GBC
*FDS

Important note: There is a also a menu option for GCN disc images, but it shouldn't be used as it causes the program to produce incorrect hashes. However, GameHeader can still be used for hashing GCN disc images, as long as this option isn't selected.
