It doesn't work with Peasant Quest 2.22, because I think the PQ dev changed the game to a different type of RPGM engine.
For example: PQ only has a game.exe, www/save folder, and walkthrough folder filled with PDF walkthrough files. It doesn't have any of the other folders/files typically associated with games using the RPGM engine the CheatMaker is meant for. Examples are Treasure of N, the GameFile, and etc. Therefore, the CheatMaker will not work with PQ at all.
I tried making the CheatMenu.jps and plugin.jps files, as the CheatMarker will noted that these doesn't exist, so it cannot install the cheat. Nevertheless, the cheat menu will not pop up. I attempted the GameFile replacement, but it will overwrite all the hidden PQ files and in effect replaced PQ with the non-existing game.
