Well, the program is pretty much straight forward, but also only necessary, if you do have a rgss file in the game folder. This decrypter unpacks three rgss type files. For RPG-Maker XP it's rgssad, for VX it's rgss2a and for VX-Ace, with which this game was made with (and most others nowadays), it's rgss3a.
- Open it
- File > Open File
- Select the rgss3a and open it
- Tools > Extract All Files
- Go into the "Extract" sub folder of the decrypter's folder
- Move all folders into the game folder and overwrite if asked
- Delete the rgss3a or back it up outside of the folder
Now, all that is left to do is, to move the "Data" folder in the "nm2nd0.7.rar" into the game folder and overwrite the one that's already there, as well as the files inside it.
