BattleShip: an AI-assisted Super Smash Bros. native port

Ports the existing Super Smash Bros. N64 decompilation using libultraship and Torch. The author’s earlier README describes agent-built graphics/audio comparison tools and differential debugging against emulator behavior, rather than claiming AI recovered the game from a cartridge without prior community work.

Requirements and limitations

  • Requires the user’s own Super Smash Bros. N64 dump matching a documented hash: US NTSC-U v1.0 (NALE) or Japanese v1.0 (NALJ). Each region is a separate build; Torch extracts assets locally during a source build or on a packaged build’s first run.
  • The README lists native Windows, Linux, Apple Silicon macOS and Android builds; native C mods and the GameCube adapter driver are desktop-only. BUILDING.md covers desktop source builds with Git/submodules, CMake and Python 3, plus Ninja on Linux/macOS or Visual Studio 2022 and the Windows SDK on Windows.
  • The author reports developing the port alone with Claude until v0.3-beta and says it is no longer a pure AI project, crediting community testing, fixes and features. These statements are self-reported; ROM identity checks and described rendering/audio comparisons do not prove complete behavioral equivalence.
  • The LICENSE grants MIT only to port-specific code, build scripts, tools and docs. The decomp submodule and decomp-derived files defer to the upstream decompilation, which publishes no explicit license; libultraship/Torch, bundled fonts and controller mappings keep their own terms; game rights are separate.
  • This review read documentation and license scope only, without a game dump, build, emulator session or independent runtime reproduction. REA use is not established.
