Standalone Pokémon Let’s Go Mods

These are single-purpose mods for Pokémon Let’s Go designed to enhance the game experience. They are designed for use with Atmosphère CFW’s LayeredFS feature.

For my recommended bundle of mods as well as my Trainer Difficulty mod for Let’s Go, check out Let’s Go! Polished Pikachu and Enhanced Eevee.

Installation Instructions

  1. Download the zip file for the mod you want and extract the “atmosphere” folder to the root of your SD card.​
  2. Boot up your Switch with Atmosphere CFW. If you’re not currently using Atmosphere CFW, I recommend setting it up with this guide.​
  3. Load up Let’s Go Pikachu or Let’s Go Eevee (all mods apply to both versions). These mods work on cartridge or eShop copies of Let’s Go.​
  4. Enjoy the mod!​
  5. To uninstall, delete the “atmosphere/titles/010003F003A34000” and “atmosphere/titles/0100187003A36000” folders from your SD card.​
  6. If you are using another CFW, such as SX OS or ReiNX, you need to rename the “atmosphere” folder to whatever that CFW expects for LayeredFS. I offer absolutely zero tech support for CFWs other than Atmosphere. ReiNX in particular is known to break with LayeredFS Let’s Go mods.​

Alternate Trade Evolutions

  • This mod allows all Trade Evolutions (and Meltan) to evolve via level up.
  • Trade Evolutions can still evolve by being traded.
  • Any Pokémon evolved with this method will appear as “hacked” until it has been traded at least once.
  • There are two versions: Lv35 and Lv50. Choose according to your preference: Level 35 is approximately around the Rocket Hideout and Level 50 is approximately after you get the sixth badge.

Expanded Encounter Tables

  • This mod makes changes to the Wild Encounter tables of the game.​ Three versions are available.
  • Version Exclusives” adds Let’s Go Pikachu’s exclusive Pokémon to Let’s Go Eevee, and vice versa. It removes Oddish/Bellsprout from Route 1 for version parity. Full encounter list here and also included in the download.​
  • Wild Gifts” includes the same changes as “Version Exclusives,” but also adds Hitmonchan, Hitmonlee, Lapras, Porygon, Omanyte, Kabuto, and Aerodactyl to the wild. Full encounter list here and also included in the download.​
  • 151” includes the same changes as “Wild Gifts,” but also adds Mew as a rare encounter in Cinnabar Mansion. Full encounter list here and also included in the download.​
  • Version-Exclusive Pokémon captured in the incorrect version will flag as hacked due to improper origin game.​
  • Gift Pokémon captured in the wild will flag as hacked.​

Altered Experience Gain

  • This mod globally alters the Experience yield of every species encountered throughout the game. In the base game, your team is consistently 5%-10% higher level than the opponent’s team, making most battles a cakewalk.
  • Note that the self-correcting effect of the modern Experience Formula will make EXP reduction less drastic than it seems!
  • 60% is the recommended version. By my projections, this should have your team consistently 2%-6% weaker than the opposing team, with absolutely no grinding. Realistically, catching Wild Pokémon will make this a smaller gap.
  • 35% is a major reduction, designed to make co-op less of a curb stomp. This version is not recommended for use in a normal playthrough, but if you want to share the game with a friend without being incredibly overleveled and teaming up on the opponent, go ahead and use it! Your Pokémon should be consistently 15%-25% weaker than the opponent’s, but you get to have two out at once.
  • 200% is designed to make post-game grinding a lot quicker. Note that the cap on EXP yield is a base value of 255, therefore any Pokémon with a base EXP value of 128 or higher will not be fully doubled. These Pokémon are instead set to 255 EXP yield. It is not recommended to use this patch while playing through the main story, as it will absolutely trivialize all content.
  • 0% is designed for a hardcore challenge that necessitates frequent new captures and strategy to overcome a massive level disadvantage. An example of the 0% EXP challenge is here (Emerald).
