Pokemon Yellow Legacy is a Gameboy ROM Hack by TheSmithplays based on Pokemon Yellow. It was last updated on May 14, 2024.

Description

The Yellow Legacy project is the prequel to Crystal Legacy by content creator Patrick Smith (TheSmithPlays), and the second project in his planned Legacy series. It is based on the Pokemon Yellow disassembly. The Legacy project is focused on changing the base game in a way that adds quality of life additions and better balancing with the benefit of twenty years of hindsight.

The primary goal of each mod is to keep the original feeling of the game while still making meaningful improvements for the player. This means that certain idiosyncrasies of the first generation of Pokemon games will remain, as they are considered an essential aspect to the core experience.

Yellow Legacy aims to give each Pokemon a special niche. Balance changes were made with the intent to keep the first generation of Pokemon feeling similar to their original incarnations, while also guaranteeing that using your favorite Pokemon will not significantly handicap your journey through Kanto.

As the intent is to maintain the feeling of the Generation 1 games, Yellow Legacy will not change core aspects of the battle system such as the sleep status, critical hit chance being based off of speed, or the overpowered functionality of trapping moves such as Wrap or Fire Spin.

While Yellow Legacy is not designed as a “Kaizo” project, Pokemon trainer fights (especially bosses) throughout the game have been made more difficult. Difficulty is used as a tool to make the game as engaging as possible to the most amount of players. It will not be difficult for the sake of being difficult, but rather, to provide you with a challenge that gives reaching the title of Champion a feeling of genuine earned satisfaction.

Major trainers will have Pokemon and attacks designed to counter players attempting to easily sweep through the fight with a single super-effective Pokemon. However, players will also have more opportunities to create unique teams of stellar Pokemon to tackle each major fight.

Pokemon availability has also been altered throughout the world to provide appropriately-powerful Pokemon based on your progression through the game. Finally, all 151 Pokemon will be obtainable in a single playthrough, and a small amount of post-game content has been added as well.
