About This ROM Hack
Pokémon Magical Altering Gym Menagerie is a short but dense puzzle and exploration challenge that takes place entirely inside a unique experimental Gym. Rather than progressing through routes and towns like a traditional Pokémon game, the entire experience revolves around solving puzzles, exploring alternate dimensions, and battling trainers inside a single complex map system.
The hack uses Skeli’s Dynamic Pokémon Expansion and Complete FireRed Upgrade (CFRU), which means it includes modern battle features such as improved AI, Fairy typing, and additional Pokémon mechanics from later generations.
One of the most important aspects of the hack is its Teleport mechanic, which has been completely reworked. Instead of sending the player to the last Pokémon Center, Teleport sends the player to different dimensions depending on the held item of the Pokémon using the move.
The game is relatively short if played quickly, especially for speedrunners who aim to reach the credits immediately. However, if players explore the optional content and complete many of the extra challenges, the experience can become significantly longer than the developer’s previous contest entry.
There is also a large amount of optional content, and the game is designed in a way where the player decides when they are finished rather than ending strictly at the credits.
Story Overview
Welcome to the Magical Altering Gym Menagerie, also known as MAGM.
This experimental Gym is not yet approved by the Pokémon League, but it has been designed as a challenge meant to test both your battle skills and puzzle-solving ability.
Your goal is simple: collect 8 pins scattered throughout the Gym to earn the right to challenge the Gym Leader, Sothoth.
However, there is a twist.
There are actually more than 8 pins available, meaning you are not required to complete every challenge inside the Gym. You are free to explore different areas, attempt different puzzles, and decide which challenges you want to complete to qualify for the Gym Leader battle.
Sothoth herself acts as a guide throughout the challenge. She frequently comments on your progress and provides helpful dialogue and hints if you are unsure what to do next. Talking to her regularly is encouraged.
Before starting the challenge, you must sign a waiver acknowledging that MAGM Inc. is not responsible for injuries, lost items, lost persons, dimensional displacement, or sudden dimensional implosions.
With that out of the way, you are free to begin exploring the Gym and discovering its many strange and unpredictable dimensions.
Key Features
- Teleport-Based Dimension System: Teleport has been completely redesigned. Instead of returning to the last Pokémon Center, the move sends the player to different areas depending on the held item of the Pokémon using it.
- Type-Based Dimensions: Type-boosting items such as Mystic Water, Charcoal, or Poison Barb send the player to alternate dimensions themed around their respective Pokémon types.
- 18 Unique Type Dimensions: There is a dedicated dimension for each Pokémon type, each containing puzzles, trainers, and a collectible pin.
- Optional Content Structure: There are more pins available than required. Players only need eight pins to challenge the Gym Leader, meaning more than half of the game’s content can be optional.
- Secret Dimensions: Special items unlock hidden areas that are not directly tied to Pokémon types, including a unique Pikachu-themed dimension.
- Secret Final Challenge: After defeating the Gym Leader and earning the MAGM Badge, players can access a hidden dimension containing a secret boss and additional ending content.
- CFRU Engine Features: The hack uses Complete FireRed Upgrade, which introduces modern battle mechanics such as ability pop-ups, improved trainer AI, Fairy typing, EV-trained trainers, and mechanics from later generations.
- Pre-Built Competitive Teams: The player begins the game with a fully prepared team of Pokémon as well as additional Pokémon stored in the PC.
- Unbound Cloud Compatibility: The game is compatible with Unbound Cloud, an online storage system created by Skeli that allows players to store and transfer Pokémon between compatible ROM hacks.
- Large Pokemon Roster: The hack supports 898 Pokemon, ranging from Bulbasaur all the way to Calyrex and their alternate forms. Hisuian forms are currently not supported.
Known Bugs & Issues
- No major bugs are currently documented in the available information.
- The contest version received post-release bug fixes and cleanup, suggesting that known issues were addressed after the initial competition release.
