Pokemon Crystal Ultimate ROM

Pokemon Crystal Ultimate is a GBC ROM Hack by Major Agnostic based on Pokemon Crystal. It was last updated on May 20, 2023.

Description

The goal of Pokemon Crystal Ultimate is to be the ultimate Pokemon Crystal experience for fans: same story, same Pokemon, and same locations, but the game is more playable, balanced, and challenging. Just about everything is viable now due to a thorough revision of moves, learnsets, base stats, and Pokemon availability. The game’s challenge has been increased by revamping the level curve and adding to trainer parties custom moves, DVs, and stat experience, as well as providing a greater variety and number of Pokemon to their teams.

Features

• Map changes that bring previously unimpressive areas to life (e.g. Victory Road in the first screenshot) and add convenience, such as the Goldenrod shortcuts
• Reworked in-battle and overworld sprites for notable characters and Surfing, as well as for Pokemon in the party menu and overworld
• Added evening as a time of day with a golden hue
• Convenient features such as being prompted to reuse Repels, resuable TMs, new gen 1 (GENWUNNERS) move tutors, a move reminder, and a Pocket PC
• More item variety and accessibility, such as a Lucky Egg early on, rare items found as milestone gifts in your room, all decorations can be obtained outside of Mystery Gift, and fossil Pokemon are found in the Ruins of Alph
• Brand new Kanto storyline based on existing lore to liven up the region; the first part of this new story is playable in v.1.0.7 (see my Discord linked below)
• Over 90 new trainers added to the game
• New music and softer night versions for all outdoor themes
• Hold B to run
• Cross-region Fly
