Kanto at its Max (and Beyond!)

Pokemon Extreme Yellow is a difficulty romhack of Pokémon Yellow featuring much tougher battles; complex dungeons; restored content; more elaborated, deeper, and darker lore and story; completely new areas and story arcs; virtually infinite post-game content; a plethora of customization and randomization options.

Features/Changes

The driving principle of Extreme Yellow is to provide “Kanto at its max (and beyond!)”:

  • all Pokémon-related to the original 151 via evolution, so pre-evo, evo, branched evo, etc (this comes with the introduction of the post-gen-1 types) for a grand total of beyond 200! This includes some surprises! More info to come!
  • wider movepool with moves from more recent generations
  • higher difficulty: all “named” trainers have a full team, with max Stats and DVs
  • various new locations, including two new cities, secret areas, new buildings, etc
  • two new story arches taking place in the middle of the main canon story
  • multiple optional subquests
  • selected trainers engage in Inverse Battles
  • possibility to complete a Living Dex via enhancement of the encounter tables
  • new items, like Heavy Ball and Fast Ball
  • revisited and expanded the backstory and psychology of the main characters
  • vast (virtually infinite) and challenging postgame, including rematches, new areas, new trainers, and more
  • non-binary gender selection
  • a plethora of QoL: improved move info box; improved Safari Zone experience; options for regulating level scaling, badge boost, and exp gaining; modern-like usage of field moves; portable PC, etc
  • enhanced interaction with Pikachu: friendship plays a pivotal role and a new custom overworld Fly animation
  • many Easter Eggs, references, and optional secrets

More changes (WARNING! CONTAINS SPOILERS!)

  • Mega Evolution appears as permanent evolution in Extreme Yellow
  • the Legendary Birds are unlocked after completing three special subquests
  • an NPC that appears randomly in any city after besting the League, and is in search of the final member of their ultimate interdimensional team
  • The author themself (yes, me!) makes an appearance as a fightable post-League boss
  • the so-long-sought super fusion Venustoise is finally catchable
  • Celadon Hotel has available rooms
  • a whole new location, the Lunar Temple, will play a key role in the main plot
  • Mt Moon has been expanded to be part again of the main plot with a new, much harder maze
  • Stater Pikachu obedience is based on happiness rather than level and number of badges, and at high happiness it will gain extra power
  • a Light Ball is hidden in the region, doubling the damage of the Starter Pikachu
  • Pikachu can Surf and Fly, and it has custom animations and sprites
  • possibility to surrender in trainer battles
  • multiple rumors and urban legends have been merged to create the ultimate end-game maze…

Rainbow Metal Pigeon (Creator)

  • pret (Pokémon Reverse Engineer Team) first and foremost, as they enabled me to work on this project in the first place
  • Vortiene, for their invaluable help, suggestions, teaching, and support over the months; this game would have likely never seen the light of day without their help (their contributions include, but are definitely not limited to: code to give trainers’ Pokémon Stat Exp; code to have the elevators’ wirring depend on the number of traveled floors; code to expand the number of hideable sprites; code to allow instant re-usage of Repellent; directions on how to free needed memory; too many to be counted times when they taught me about assembly, Game Boy architecture, and RBY framework)
  • jojobear13, for their precious technical insights and open-source bug fixes (the code to give trainers’ Pokémon Stat Exp was originally developed by them; they provided fundamental insights on a pesky TM-related bug; they implemented a new and better RNG)
  • Porygondolier, not only for being a very pleasant and interesting person to interact with but also for working with me on the mid-battle evolution (admittedly, they did most of the job!)
  • Sanqui, for granting usage on the gen1-style sprites used in their Pokémon Red randomizer; all sprites that are not the original 151, Kleavor, Annihilape, Mega Evolutions, Anomalies*, MissingNo, or taken from Gold/Silver, are taken from their project; detailed credits to single artists can be found on their website
  • Plague Von Karma, for some suggestions on speed-ups, providing the move deleter/relearner code (which uses code from jojobear13, based on Mateo’s code), as well as Kleavor and Annihilape sprites (I modified the latter)
  • FrenchOrange, mauvesea, and LJSTAR, for their many many improvements and fixes on the sprites I drew; FrenchOrange drew the Flying Pikachu sprite
  • Xillicis, for their tutorial on how to increase the number of usable Pokémon, as well as many useful exchanges over the months, and for some back sprites: Electivire, Tangrowth, Rhyperior, Lickilicky, Magnezone, Porygon-Z, Magmortar
  • ZetaPhoenix, for the TM name displayer code
  • BlueZangoose, Mord, and Cram-O-Dev for having helped, supported, and motivated me and just being great people during this adventure of mine
  • Mega Evolution, Eternamax Eternatus, Arceus, and Venustoise sprites are my own production, bar the aforementioned help
  • Mega Rayquaza and Zygarde Complete sprites are from Axel-Comics:https://www.deviantart.com/axel-comics
  • Ultra Necrozma sprite is from SageDeoxys:https://www.deviantart.com/sagedeoxys
  • Pokémon overworld sprites that are not from the original Green/Blue/Yellow are from Crystal Clear via the help of FrenchOrange
  • Overworld sprites of the gym leaders are from: Brock: Vortiene; Misty: Vortiene; Lt Surge: Mord; Erika: Mord; Koga: Game Freak (Gold/Silver); Sabrina: Vortiene; Blaine: Game Freak (Gold/Silver); Giovanni: Game Freak (Green/Blue)
  • Green sprites are from Ghost-MissingNo:https://www.deviantart.com/ghost-missingno/art/Blue-Sprites-for-R-G-B-Y-339796334
  • Yellow sprites are from LouLilie:https://www.deviantart.com/loulilie/art/PokemonSpecial-Sprites-Yellow-302559354
  • overworld non-vanilla sprites (legendary birds, Slowking, etc) are from Crystal Clear
  • Game Freak, Creatures Inc., Nintendo, and TPCI for creating Pokémon
  • PLEASE CONTACT ME (Rainbow Metal Pigeon) if I forgot to add your name for anything of yours that I have used!!! In which case I first apologize, and then I’ll put a remedy as soon as possible!

(*) “Anomalies” refers to Zygarde Complete, Ultra Necrozma, Mega Rayquaza, Eternamax Eternatus, and Arceus.
