N64 Games
Each Nintendo 64 game here has its own page with what the community has made for it: native PC ports, and texture packs that replace the original graphics.
PC ports come in two kinds. A decompilation port is built from the game’s code rewritten by hand as C, which makes it easy to change and mod. A recompilation port is made by a tool, N64: Recompiled, that translates the game’s machine code automatically. Both run as a normal PC program without an emulator, and both need a ROM dumped from your own copy of the game.
See every port at once on the N64 PC Ports page, or every pack on the N64 Texture Packs page.
