# lp-engine: rebuilding the LovePlus+ runtime

> lp-engine runs the Nintendo DS game LovePlus+ on desktop systems using the player’s own Japanese game dump. Its Rust runtime executes the original game logic while recreating graphics, sound, input, clock and save services, with higher-resolution rendering and an English translation delta. Research notes document the script VM, game flow and save format.
