Recompiled Animal Crossing (GameCube) into a native PC port with Claude

ac-plus is a native PC port of the GameCube title Animal Crossing, built upon the ACGC-PC-Port project which utilizes the ac-decomp decompilation. The project incorporates various quality-of-life features and assets from Animal Crossing: City Folk, including skyboxes, character animations, music, and sound effects. The author reports that Claude Opus 5.5 was used to write code for the project, while noting that no AI-generated art, models, or sounds are included. The game requires the user to provide their own USA revision 0 disc images for both Animal Crossing (GameCube) and Animal Crossing: City Folk (Wii). Upon the first launch, the software converts necessary assets from the City Folk disc. The port supports Windows natively, while Linux and Steam Deck users run the executable via Wine or Proton. Experimental online multiplayer is included, allowing up to four players to visit towns. The project maintains compatibility with Redump-verified disc images, though the City Folk Nintendo Selects re-release remains untested. Documentation for setup and disc verification is available at https://raw.githubusercontent.com/bwahfox/ac-plus/HEAD/README.md.
