# Animal Crossing: a native PC port of the GameCube decompilation > Runs Animal Crossing’s decompiled GameCube C code natively on 32-bit x86, replacing the GX graphics API with an OpenGL 3.3 translation layer and console services with SDL2-based platform code. Game assets are read at startup from the user’s own disc image instead of being shipped. It is a port built on ACreTeam’s ac-decomp, not a matching rebuild of the original executable. - Type: Case study - Targets: Game - Category: Independent reconstruction cases - Relationship: Independent reconstruction project - Sources reviewed: 2026-10-18 - Added to the catalog: 2026-10-18 - Original resource: - Primary source: - Catalog page: - Record JSON: - Chinese version: [简体中文](https://awesomerea.org/zh/resources/animal-crossing-pc-port-case/index.md) ## Requirements & limits - **Prerequisites:** Requires the user’s own Animal Crossing (USA) disc image in ISO, GCM or CISO form; at startup the port loads main.dol, foresta.rel.szs and about 2,500 assets from it in memory. The README states that the repository contains no game assets or assembly. Saves use Dolphin-compatible GCI files, and optional HD texture packs use Dolphin’s naming format. - **Prerequisites:** Windows is the primary target: the documented build uses an MSYS2 MINGW32 shell with 32-bit MinGW GCC, CMake 3.16+ and SDL2, plus vendored GLAD for an OpenGL 3.3 Core context. Builds must be 32-bit, unoptimized (-O0) and define NDEBUG, because the decompiled code casts pointers to 32-bit values and contains optimization-sensitive undefined behavior. Linux i686 is described as compiling and linking but is not officially supported. - **Scope:** The reviewed snapshot is the v0.9.3-playtest pre-release and supports only the USA Rev 0 release (GAFE01_00). The README calls the underlying ac-decomp complete, while the developer documentation calls it 99.52% complete. Online play is not planned, and the Animal Crossing Deluxe mod is incompatible, although this release adapts some of its quality-of-life changes. - **Testing evidence:** About 100 decompilation files carry TARGET_PC changes, and optional PC_ENHANCEMENTS add settings, MSAA and texture-pack loading. The project describes Windows as fully tested and records an unresolved bass-distortion audio issue, but publishes no automated tests or byte-matching checks for the port. - **License:** LICENSE keeps the decompilation code under CC0 1.0 from ac-decomp and licenses the pc/ layer and TARGET_PC additions under MIT, with a separate MIT notice for FixNES; GitHub classifies no single license. Game content rights are separate. The README discloses that AI tools such as Claude were used for port code only. ## Primary sources 1. 2. 3. 4. 5. 6. 7. ## More in Games - [Atlantis Native: porting the Atlantis and Atlantis II engines to Rust](https://awesomerea.org/resources/atlantis-native-case/index.md) · Case study - [BattleShip: an AI-assisted Super Smash Bros. native port](https://awesomerea.org/resources/battleship-port-case/index.md) · Case study - [Budokai Tenkaichi 3: a native PC port built on a matching decompilation](https://awesomerea.org/resources/tenkaichi3-pc-port-case/index.md) · Case study - [Cosmo: a native port of Cosmo's Cosmic Adventure](https://awesomerea.org/resources/cosmo-native-port-case/index.md) · Case study - [CTR Turbocharged: a PC sourceport built on the Crash Team Racing decompilation](https://awesomerea.org/resources/ctr-turbocharged-port-case/index.md) · Case study - [d2mac-linux: porting the Diablo II Mac executable to 32-bit Linux](https://awesomerea.org/resources/d2mac-linux-case/index.md) · Case study ## About this entry The description was reviewed against primary sources.
