those badge aracde cheats had stop working even before they make the plugin
it won't work even if you try it one million times
and read the instructions how to use those plugins
When you're using a plugin, if you have the green flash but no game plugin entry in the ntr menu, Press Select in game as it should be said on the first post, the readme etc...
Try to check the following:
- If the cheat have a pre requisite
- If you have the good region of the cheat
- If you have the good version of the game (update)
