About This ROM Hack
Pokémon Emerald: Pit of 100 Trials is a full-region endurance challenge hack where the entire Hoenn region functions as a continuous gauntlet. Unlike traditional Pokémon gameplay, this ROM removes most safety nets such as Pokémon Centers and frequent marts, forcing players to survive 100 consecutive high-level battles using limited resources and one fixed team.
The hack focuses on resource management, teambuilding, and long-term strategy, while still giving players tools like infinite Master Balls, fast EV training, and move tutors to reduce unnecessary grinding.
Story Overview
Welcome to Hoenn—but this is not the Hoenn you remember.
The entire region has been transformed into the Hoenn Pit of 100 Trials, where each trial consists of battling powerful trainers using Level 100 Pokémon. Progressively, you will face tougher opponents, including Gym Leaders with full teams of six, followed by the Elite Four, the Champion, and 10 secret boss battles designed to push your endurance to its absolute limit.
Healing is limited strictly to the items you carry, and once you enter the Pit challenge, there is no turning back. If you white out at any point, the challenge ends in a game over.
Key Features

Useful Resources- Pick up the Poké Ball on Route 101. You will have a starting Crobat, but you don't have to use it.
- Everything you will need is in a bag in Oldale Town. Interact with it and you will receive Master Balls, Vitamins, Heart Scales, and other items.
- Talk to the man with the microphone. He will give you all the TMs and HMs.
- Oldale Town has a Pokémon Center, Department Store, Move Reminder, Move Deleter, Name Rater, and the area where you can catch Pokémon.
- There are EV checkers and IV checkers in Oldale Town's Pokémon Center.
- If you cannot find a particular dual−typed Pokémon, then check the areas related to that Pokémon's other type.
- Aim for optimal natures and IVs. You can check your IVs at the Oldale town Pokémon Center.

- Revives are the most important item in this game, so buy enough of those!
- Leftovers are probably your best-held item.
- If you think you are not going to use a TM, or HM08 Skill Swap, you can sell it for 10 extra PokéYen.
