skate3recomp — NixOS package

Nix packaging for skate3recomp, an unofficial native recompilation of the Xbox 360 version of Skate 3 for Windows and Linux.

You must own a legitimate Xbox 360 copy of Skate 3.
This package does not include retail game files.

Files

File	Purpose
`package.nix`	`stdenv.mkDerivation` derivation (nixpkgs-style)
`default.nix`	Entry-point for `nix-build` / `nix-shell` local testing

Before you build — get the SHA256 hash

The hash field in package.nix is a placeholder. Fill it in by running:

nix store prefetch-file --hash-type sha256 --unpack \
  https://github.com/mchughalex/skate3recomp/releases/download/v1.0.4/Skate3Recomp-Linux.zip

Paste the printed sha256-… value into the hash = line in package.nix.

Local test build

# Build (requires allowUnfree — the upstream has no OSS licence)
NIXPKGS_ALLOW_UNFREE=1 nix-build

# Run directly from the result symlink
./result/bin/skate3recomp

NixOS module / overlay usage

Add this to your flake or configuration:

# flake.nix (packages output)
packages.x86_64-linux.skate3recomp = pkgs.callPackage ./skate3recomp/package.nix { };

# or as an overlay
nixpkgs.overlays = [
  (final: prev: {
    skate3recomp = final.callPackage ./skate3recomp/package.nix { };
  })
];

# then in environment.systemPackages or home.packages:
environment.systemPackages = [ pkgs.skate3recomp ];

Runtime setup

On first launch the app shows a file-picker dialog to select your Skate 3 ISO. Game data is extracted to ~/.local/share/skate3recomp by default.

To use a custom location, set SKATE3_DATA_DIR before launching:

SKATE3_DATA_DIR=/mnt/games/skate3 skate3recomp

The wrapper also passes --input_backend=sdl automatically, which is the correct mode for Linux (matches the upstream run-linux.sh script).

Controller input

An Xbox controller is the recommended input method. DualShock and other controllers work through SDL's generic XInput mapping. Keyboard controls can be enabled in the in-game settings menu (Escape to open).

AMD GPU (RX 580) notes

The game uses Vulkan. Your system needs amdvlk or mesa (radv) in hardware.opengl.extraPackages / hardware.graphics.extraPackages (NixOS 26.05+):
```
hardware.graphics = {
  enable = true;
  extraPackages = with pkgs; [ amdvlk mesa.drivers ];
};
```
RADV (Mesa) is generally preferred over AMDVLK for this type of workload.
If you see a blank screen on Wayland, try forcing X11: SDL_VIDEODRIVER=x11 skate3recomp

Troubleshooting

Symptom	Fix
`error: ... is not licensed`	Set `NIXPKGS_ALLOW_UNFREE=1` or add `nixpkgs.config.allowUnfree = true`
`libvulkan.so.1: cannot open`	Add `vulkan-loader` to your system packages or check GPU driver packages
`librexruntime.so: cannot open`	The wrapper sets `LD_LIBRARY_PATH`; if running the binary directly, set it manually: `LD_LIBRARY_PATH=$out/lib/skate3recomp ./skate3`
App opens but no ISO dialog	Make sure `gtk3` is available; it provides the file-picker
Audio crackling	v1.0.4 fixed most audio issues; if it persists, try `SDL_AUDIODRIVER=pipewire skate3recomp`
Wayland black screen	Set `SDL_VIDEODRIVER=x11` to fall back to XWayland

How autoPatchelfHook works here

The zip contains two prebuilt ELFs compiled on Ubuntu 24.04:

skate3 — the main executable
librexruntime.so — the rexglue runtime shared library

autoPatchelfHook patches both binaries' RPATH and interpreter (PT_INTERP) so they resolve against the correct Nix store paths rather than /lib/x86_64-linux-gnu/. The wrapper then adds $out/lib/skate3recomp to LD_LIBRARY_PATH so skate3 can find librexruntime.so at runtime.

No AppImage, no SquashFS offset, no FHS env needed — the zip is a plain ELF bundle.
