SpaghettiKart the Mario Kart 64 fan-made PC port gets a big upgrade

The Harbour Masters team recently released a big upgrade for SpaghettiKart, their Mario Kart 64 fan-made PC port with a bunch of new features.

Like other PC ports of retro Nintendo games, you need to supply your own copy of the game as they do not supply the assets to actually play the games. Which is how they hope to keep Nintendo lawyers away. With the 1.0.0 release there's a new harder CPU difficulty, improvements to the camera, a better custom track system, performance improvements and much more.

The full list of what's changed in version 1.0.0:

• Added minimap to Harbour and multiple Harbour scene updates.
• Implemented Harder CPU, including Spiny Shell, Triple Shells, and major item logic fixes.
• Added Digital Speedometer and new Rulesets system.
• Major frame interpolation overhaul (karts, UI, 3/4P, translucent meshes).
• Large camera refactor, including Track Tour Camera and FOV restructuring.
• Expanded and refactored Custom Track system (render layers, finish line, higher limits, better collision).
• Introduced new systems: RaceManager, RandomItemTable, and SpawnParams.
• Added Sky & SkyActors and various visual enhancements.
• Significant podium ceremony and cinematic fixes.
• Wide range of gameplay bug fixes (items, multiplayer, battle mode, crashes, Lakitu, moles, etc.).
• Extensive UI and menu fixes, scaling improvements up to 400% internal resolution.
• Implemented new audio driver, plus expanded audio documentation.
• Major build & CI improvements (macOS Universal Binary, Docker, AppImage, Switch, OpenBSD, Fedora, Windows fixes).
• Performance, stability, and memory safety improvements (UB fixes, pointer fixes, optimizations).
• Substantial documentation updates (README, FAQ, BUILDING, Doxygen, custom track guides).
