It was discovered that a bug in GB Reorganizer was causing the games MoonShadow and Moonshadow to be extracted into the same folder, instead of getting separate folders with game IDs. This has been fixed, bringing the version number up tp 4.0.4.1.
Also, I have updated the supported Windows versions to 8, 10, and 11. It probably works on older versions going back to Windows XP, but I won’t be doing any testing on those.
