Conker's Bad Fur Day: Recompiled

A native PC port of Conker's Bad Fur Day (N64, US version). It's built by statically recompiling the game with N64Recomp, starting from the Conker decompilation. It runs on N64ModernRuntime and is rendered by RT64.

This repository contains no game data. You need your own legally obtained copy of the US ROM. Everything from the game is extracted from that ROM on your machine during the build.

Download

Ready-to-play Windows, Linux and macOS (Apple Silicon, macOS 15 or later) builds are on the Releases page. Unpack one anywhere, run ConkerRecomp, and pick your US ROM in the launcher the first time. The packages contain no game data: you still need your own ROM. The macOS app isn't signed with an Apple developer ID, so the first time, open it and then choose Open Anyway in System Settings > Privacy & Security. To build it yourself instead, read on.

Features

  • Runs natively on Windows (Direct3D 12 or Vulkan), Linux (Vulkan) and macOS (Metal), rendered by RT64. Supports higher resolutions, widescreen, anti-aliasing and high frame-rate presentation.
  • Game controllers and keyboard, with remappable controls and rumble.
  • Full audio: music, sound effects and the voice acting.
  • Saving (EEPROM), stored per user.
  • A launcher with settings, controls and a mod menu (RecompFrontend, as in Zelda 64: Recompiled and Banjo: Recompiled).
  • Mod support (.nrm mods: function patches and hooks). Three mods are included: Skip Intro, Skip Any Cutscene and Cheats.

Status

The game is playable, and has been played through to the end. Known issues:

  • Widescreen: the pause menu's blurred background is the 4:3 frame scaled up to the full width, so its top and bottom are cropped.
  • Environment-mapped (reflective) surfaces render without their reflection texture.
  • Frame rates above 30: characters snap once when the game changes how many parts it draws them with, a few times a minute, and the camera can blend across a cut.
  • Only the US ROM is supported (and ROM hacks that only change its assets: see ROM hacks).
  • Linux: the build and the game have been tested on Ubuntu 24.04 under WSL, with software Vulkan (llvmpipe) and sound. It hasn't been played on Linux with a real GPU driver yet, so reports are welcome, especially about performance or audio (under WSL the sound crackles while the software renderer loads the CPU).
  • macOS: the build has been tested on an Apple M3 Pro with macOS 27 and Xcode 27, and the game starts and runs with Metal. It hasn't been played through on macOS yet, and Intel Macs haven't been tried.

If the game crashes on Windows, a report is written to crash.log next to the executable and shown in a message box. On Linux and macOS, the crash report is printed to the terminal. Please include it when reporting a problem.

What you need to build it

  • The US ROM of Conker's Bad Fur Day in big-endian .z64 format, with SHA-1 4cbadd3c4e0729dec46af64ad018050eada4f47a. It is never committed: the build extracts what it needs from your copy.
  • A folder path without an apostrophe (') to clone into. Some of RT64's build steps break on one.
