Pokemon Peridot ROM

Pokemon Peridot is a GBC ROM Hack by Sea Tree based on Pokemon Crystal. It was last updated on January 06, 2025.

Description

Pokemon Peridot is a hack created using the pokecrystal disassembly project from pret. Taking place in a wholly original region, this release features 8 gym leaders and the Pokemon League, along with postgame rematches and a Battle Subway. This hack also features a selection of previously unused Pokemon designs from various points in Pokemon Gold & Silver’s development. These Pokemon were given fanmade stats to make up for the lack of finalized ones.

Features

General

• A brand-new region for the player to explore.
• Previously unused Pokemon from various points in Gold & Silver’s development. These feature fanmade names, stats, and typing.
• The player will have two rivals. Both will challenge the player to a battle periodically(Only one per character in this demo).
• Shiny Pokemon will have a Defense and Special DV of 15, the Attack DV calculation remains the same as regular Generation 2 games. Speed is not taken into account at all. This results in a 1/512 shiny chance.
• Borrowing from Pokemon Sun & Moon, certain routes will have a trainer that will refuse a challenge until every other trainer on that route is defeated.
• Move Tutors are scattered around the maps, sometimes in hidden areas. They will mostly teach moves that were exclusive to events in Gold & Silver.
• Every starter will be available through in-game trades.
• Prompt to use another repel when one runs out.

Gym Challenges

• Gyms cannot be exited until the player beats the leader or whites out. Losing will reset your progress in that gym. Bring healing items.
• Gym Leaders disallow the player from using any sort of items during battle. Berries and other held items will work as normal.
• Gyms can be completed out of order.
• Gym Leaders will have different parties depending on how much progress the player has made.

Battle

• There is no physical/special split. Dark was changed to be a physical type, and Ghost special.
• Added Fairy-type. It deals special damage.

• The X items have been revamped. They are now a held item that activates when the holder comes out, like the Berserk Gene. They are consumed on use.

Pokemon

• Movepools and stats updated to reflect modern generations.
• Some inspiration has been drawn from the Spaceworld 97 demo for movepools. (Houndour can learn Bone Club, Mareep can learn Hypnosis)
