Let's Go Recomp

A native Windows port of Pokémon: Let's Go, Eevee! and Let's Go, Pikachu! (Nintendo Switch), made by static recompilation: the game's ARM64 code is translated into C and compiled for your PC, and a runtime stands in for the Switch (system services, NVN graphics on Vulkan, audio, controllers). It is not an emulator. Built on LAS Recomp by Peiikai.

The same frame rendered by this port with the game's original settings (left) and 0.5.0's (right); below, the marked area at 2x. Not Switch captures. ▶ Showcase video

• Native code, up to 4K internal resolution, any window size, fullscreen
• Anti-aliasing SMAA, TAA or AMD FSR 3.1 (also upscales); FSR 1 for a lower resolution
• Ambient occlusion (SSAO) and indirect light (GI), smooth shadows, 16x anisotropic filtering
• The game's 30 fps, or 60 / 120 fps in the overworld (experimental), plus FSR 3.1 frame generation
• 2x interface images and sharper text
• Mods: fan translations and other LayeredFS mods, several at once
• Keyboard and mouse (aim Poké Balls, touch screen) and any controller; every key rebindable
• Experimental wild battles (a classic battle, then the capture) and skip controller selection
• Shaders cached on disk

In the game, F12 opens the same settings, applied at once:

• Let's Go, Eevee! and Let's Go, Pikachu!, any region, from your own dump (cartridge or eShop)
• 1.0.0 (the base game) for every option; the 1.0.1 / 1.0.2 updates are accepted, less tested, without the frame rate, wild battles and controller options
• .xci / .nsp files must be extracted first

Most tested with Eevee 1.0.0; Pikachu 1.0.0 less.

1. Download LetsGoRecomp-<version>-windows.zip from Releases and unzip it into a folder you can write to.
2. Open LetsGoRecomp.exe (if Windows warns, More info → Run anyway).
3. On the Game page, click Select game folder... and pick the folder with exefs and romfs.
4. Wait while it copies the files and recompiles the game for your PC (only once: 22 minutes measured on a 20-thread CPU, longer with fewer threads).
5. Click Play.

Everything stays in that folder (settings, saves, mods). To update, unzip a new release over it. For both games, use one folder each.

On the Mods page, Install a mod... takes the .zip / .rar / .7z as downloaded (Atmosphere LayeredFS packs: translations, textures, models). Tick the ones to use; where two change the same file, the higher one wins. Mods of the game's code (exefs, IPS, cheats) don't work. Tested with the Brazilian Portuguese fan translation by Pokémon Switch Brasil (not included; distributed by its authors).

• 60 / 120 fps and frame generation are experimental; battles and captures stay at 30 fps
• Wild battles don't split experience yet
• Switching to TAA while playing shows one or two black frames
• The 2x interface shows a few frames of thin stripes during an area change
• Online features, the Poké Ball Plus and the second player aren't supported
