Compression / Decompression


It is a simple program that allow you to perform several actions to edit Mario Party data with the help of Mario Party Compression Library, a library that implements the compression format used by Mario Party. It is compatible with all the versions of the game (NTSC-J, NTSC-U and PAL), but make sure that the ROM doesn’t have swapped data, or else it won’t work.


The program requires the .NET Framework 4.7.2.
