# 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.
> [!IMPORTANT]
> **No game files are included.** You need your own legally obtained copy of *Let's Go, Eevee!* or *Pikachu!*,
> extracted (the `exefs` and `romfs` folders). A fan project, not affiliated with Nintendo, The Pokémon Company, Game
> Freak or Creatures.
> [!NOTE]
> **Work in progress.** The game hasn't been played from start to finish on this port yet. Bug reports, fixes and
> improvements are very welcome: open an issue or a pull request (CONTRIBUTING.md).
