One of the longest and weirdest ROM hack names out there is Magical Altering Gym Menagerie. That’s certainly a long and uncommon name for a Pokemon hack, isn’t it?
If you’ve been playing it for a while, you might try to make some gameplay overhauls by using a list of Magical Altering Gym Menagerie cheats.

This hack focuses on Gym Battles only and not so much on catching Pokemon.
You enter an altering gym where the dynamic format will put your wits to the test. Dig deep into the Gyms and fight the big guns, and if you want to emerge at the top, perhaps you’ll need some cheats.

Cheats That Are Not Working
Wild Pokemon Modifier Cheats
The cheats for the Pokemon modifier aspect did not work during our testing. That is because they already modify the wild Pokemon you encounter. There are no wild Pokemon battles here anyway, so you cannot catch anything.
Other Pokemon Related Cheats
Since there are no wild Pokemon battles in the game, some cheats do not work for the Pokemon you fight.
The ones listed below are those cheats related to Pokemon that do not work as well as other non-Pokemon cheats:
- Nature Modifier
- Level Modifier
- Gender Modifier
- No Encounters
- One Hit Kill
Item Modifier Cheats (All Code Breaker)
Change the YYYY below to the specific item that you want. You can then withdraw an unlimited amount of those items from the Item PC:

Conclusion
Due to the unique game mechanics found in this hack, the list of codes above are the only working Magical Altering Gym Menagerie cheats we got so far.
A large chunk of cheats don’t work or cannot be tested. That’s because the game is just gym or trainer battles.
Nevertheless, the reliable ones are working like item modifiers and others to help you in your skirmishes.
Perhaps there might be some cheats that we missed that you might want to chime in on the comments.
