Pokemon Perfect Crystal ROM

Pokemon Perfect Crystal is a GBC ROM Hack by SuperEgz based on Pokemon Crystal in English. It was last updated on October 22, 2020.

Description

When Pokemon Crystal was released, it was the ultimate experience of classic Game Boy/Game Boy Color Pokémon. Now this classic can be played the way it always should have been! The goal of Pokemon Perfect Crystal has been to make an idealized definitive version of Pokémon Crystal that has every Pokémon available to catch and to fix a number of glaring glitches that hampered the original game. This is the original version, where Red has Level 100 Pokémon and encounter rates for some added Pokémon are extremely low.

Features

• All 251 Pokémon are catchable.
• Pokémon that normally evolve through trades evolve through the use of stones.
• Stones and items that could only be obtained through Mystery Gift, available at department stores.
• The GS Ball and Celebi event can be triggered after Mount Silver has been unlocked.
• Fixed a bunch of glitches, such as the problems with some of Kurt’s balls and several items.
• Increased opponents’ levels to match HGSS (Except Red, who has Level 100 Pokémon just for fun; he is supposed to be the best trainer in the world after all). This is mainly noticeable in late Johto and Kanto.
• Made all Gym Leaders rematchable. Just talk to them again, and they will ask for a rematch.
• Removed the badge boosts and the extra chances the AI has to miss on status moves to create parity between the player and the AI.
• Ho-Oh and Lugia have their signature moves when you encounter them.
• Reusable TMs.
• Hold down B to run.
• Restored Japanese sprites for the Beauty, Sage, Medium, female Swimmer, and Fisherman.
