About

A playable Nintendo DS port that combines the original game logic reconstructed by the BattleShip project with a Nintendo DS backend. It is not a new Smash-style game written from scratch, and the repository contains no Nintendo assets or ROM-derived data. The README puts the project at about 75% complete as of 2026-10-02.

How it differs from the original

The port targets 30 FPS instead of the original's 60, and four-fighter matches can dip to around 20 FPS. Loading screens are much longer than on N64, and multiplayer is limited to one console with 1 human and up to 3 CPUs.

Getting started

Bring your own legally obtained North American Super Smash Bros. ROM, a big-endian NTSC-U v1.0 dump of exactly 16,777,216 bytes. The one-command Windows build script, build.ps1, takes the ROM path and builds smash64ds.nds; it needs devkitPro and several other tools. It also runs on real Nintendo DS hardware.

Known issues & limitations

Four-fighter matches can drop to around 20 FPS; matches with one to three fighters hold 30 FPS.
Training mode, bonus-stage buttons, the ending scene and credits, the intro cinematic, and proper character unlocks are unfinished.
Random freezes still occur in some areas.
Saffron City's garage door is always open.
Loading screens can have a couple of seconds of black between scenes.
Audio can stutter during heavy matches and loading states.
The game targets 30 FPS instead of the original's 60.
