# Portémon Nitro: a HeartGold and SoulSilver engine port

> Portémon Nitro reimplements the Pokémon HeartGold and SoulSilver engine in LÖVE for PCs and mobile devices. It reads a user-owned Nintendo DS ROM, derives game data locally, and separates ROM interpretation from runtime behavior and the app interface. The repository contains Lua game code, Nintendo DS and game-specific libraries, and ROM import tooling.
