Pokémon Crystal Ultimate

Hack of Pokémon: Crystal Version


The goal of this ROM hack is to be the ultimate Pokemon Crystal experience for fans, a remaster of sorts: same story, same Pokemon, same world, but the game is more playable, balanced and challenging. There’s extra content added too as well as many QoL improvements from music to sprite work to brand new features and battle system improvements!

Just about everything is viable now due to a thorough revision of moves, typing, 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 and moves to their teams.

More or less empty locations in the original game such as Ilex Forest, Ice Path and Victory Road (to say nothing of Kanto) now have extra trainers and items. Some areas from RBY have been restored and brand new quests have been added too! Also, some liberties have been taken to spice up and rebalance gameplay, such as type changes to over a dozen Pokemon and type matchup changes inspired from other gens to balance out Poison and Steel.

Understandably, some players may find that some of these changes stray too far from what they want from this type of hack, so a Classic version of the game was made (that’s why the download includes two files). Classic removes most base stat changes, all Pokemon typing and type matchup changes, and all evolution level changes (except for Magikarp and Grimer). The specific differences for Classic are noted in the Readme (along with MUCH more information) using the highlighted Classic tag.

Enjoy the hack and feel free to check out the linked YouTube video’s description for the most recent version of the hack, and the links at the bottom of the Readme for more!

Absolutely Excellent. I haven’t enjoyed a Pokemon game this much Since Black 2’s Challenge mode. Takes Crystal and brings it as close to the modern game’s conveniences as a Gen 2 game possibly can. Outside of what’s listed on this hack’s page, here’s everything else I noticed:

  • Improved learnsets
  • More Trainers
  • Harder Trainers
  • Harder Gyms
  • Improved day of the Week Events system
  • slightly tweaked routes for better traversal

With a word like Ultimate in the title, you better deliver. This does without question.
