Hmm. In my case all work. May be i prepare files with error.
I Write step-by-step manual for install cheat module
rpg-mz-cheat-1.0.3-core.tar.gz.
1.Download this cheat, and extract to any folder (not game folder). BTW you can use winrar or 7zip for extract
2.Copy folder cheat and file cheat-version-description.json into game folder.
3.Go to folder js (in game folder), and open file main.js with notepad or notepad++
4.Add string "../cheat/init/import.js", right after const scriptUrls = [ It have to be like on attached screenshot.
Do not use main.js in cheat archive, because game has a bit not standard folders tree it will not work.
It 100% working solution. If it not work, i can upload whole game with testes and working cheat
