reshady

Interactive ReShade helper for Steam / Steam Deck. Installs ReShade, applies bundled presets, and safely removes/backs it up.

Features

• Detects Steam libraries and installed games (Deck paths supported).
• Installs/updates ReShade via reshade-linux.sh (downloaded automatically).
• Applies bundled presets (PSX CRT, Clean Bloom, Performance Sharp).
• Sets Steam launch options for Proton: WINEDLLOVERRIDES="d3dcompiler_47=n;d3d9=n,b" %command%.
• Non-destructive uninstall backs up ReShade files.

Requirements

• Bash, curl, python3, 7z, git, wine (all present on SteamOS/Deck).
• Optional: fzf for nicer selection; falls back to numbered menus.

Install

git clone https://github.com/yourname/reshady.git
cd reshady
chmod +x reshady.sh

Usage

./reshady.sh

CLI (for automation / Decky backend)

./reshady.sh list-games
./reshady.sh install --appid 377840 --game-path "/path/to/game/x64" --api d3d9 --preset presets/psx_crt.ini
./reshady.sh preset  --game-path "/path/to/game/x64" --preset presets/clean_bloom.ini
./reshady.sh toggle  --appid 377840 --game-path "/path/to/game/x64"
./reshady.sh remove  --game-path "/path/to/game/x64"

Install guide: desktop / Deck (script)

1. Clone this repo on the Deck (desktop mode) or any Linux box with Steam installed.
2. Run ./reshady.sh and pick “Install/Update ReShade”.
3. Choose the game, accept the suggested API (or pick one), choose a preset.
4. Restart Steam, launch the game, press Home to open ReShade.

Decky plugin integration (recommended flow)

• Backend: call the existing CLI commands (list-games, install, preset, toggle, remove). No extra binaries needed; the script auto-downloads reshade-linux.sh if missing and handles ReShade installation.
• Frontend wire-up:
  • On load, call ./reshady.sh list-games to populate games (format: appid|name|path).
  • “Install/Update” button -> install --appid <id> --game-path <path> --api <d3d9|dxgi|opengl32|d3d8> --preset <ini>.
  • “Apply preset” button -> preset --game-path <path> --preset <ini>.
  • “Toggle” button -> toggle --appid <id> --game-path <path> (non-destructive rename + launch option change).
  • “Remove” button -> remove --game-path <path> (backs up files).
• Ship the presets/ folder with the plugin; add a file picker that copies a user .ini into presets/ then calls preset so it shows up in-game.
• Decky backend tip: run commands with cwd set to the plugin directory so relative presets/ paths resolve.
• Restart Steam after install/toggle because launch options are written to userdata/<id>/config/localconfig.vdf.

Decky plugin in this repo

• The repo now includes a Decky plugin (backend + prebuilt frontend in dist/index.js) that shells out to reshady.sh and presets/.
• Build is optional because dist/index.js is already present. If you want to rebuild: npm install && npm run build (Node 18+), then copy dist/ back; otherwise skip.
• Install to Decky: copy/symlink the repo into ~/homebrew/plugins/Reshady, or zip the contents and drop into Decky Loader. Ensure reshady.sh remains executable (chmod +x reshady.sh); the backend runs it with cwd set to the plugin dir so presets/ resolve.
• The plugin backend exposes list_games, install, apply_preset, toggle, remove; the frontend provides buttons for each and preset/API selectors.

Decky quickstart (no build needed)

1. git clone https://github.com/samedayhurt/reshady.git && cd reshady
2. chmod +x reshady.sh
3. mkdir -p ~/homebrew/plugins/Reshady && cp -r . ~/homebrew/plugins/Reshady
4. Restart Decky Loader; the “Reshady” tab should appear with game picker, preset/API selectors, and Install/Toggle/Remove buttons. Main menu options:
5. Install/Update ReShade – choose a game; script suggests an API from a known list (else prompts), then pick a preset.
6. Apply preset only – reuses existing ReShade install and just swaps the preset.
7. Remove ReShade (backup) – moves ReShade files to reshady_backup_<timestamp> inside the game folder.
8. Add custom preset – copies any .ini you point to into presets/ so it appears in the chooser.
9. Toggle ReShade on/off – renames the injected DLL and adds/removes the launch option (non-destructive, keeps presets intact).

Bundled presets

• psx_crt.ini – CRT scanlines/curvature + light film grain + mild bloom (needs CRT_PSX.fx copied automatically).
• clean_bloom.ini – subtle HDR bloom + clarity.
• perf_sharp.ini – lightweight sharpening only.

Notes

• The script copies CRT.fx to CRT_PSX.fx in the merged shader folder so the CRT preset shows up.
• Steam launch options are written to userdata/<id>/config/localconfig.vdf. Restart Steam after running.
• For non-default Steam library locations, the script reads libraryfolders.vdf automatically.
• API suggestions: map covers FFIX/FF7/FF8 (d3d9), Monster Hunter: World / Elden Ring / Cyberpunk (dxgi). Others will prompt you to choose (d3d9, dxgi, opengl32, or d3d8).
• Toggle is non-destructive: it just renames the override DLL (d3d9/dxgi/opengl32/d3d8) to .reshady.off and removes/restores the launch option.
• Adding presets: drop any ReShade preset .ini into presets/ or use “Add custom preset”. Sources: reshade.me forums, NexusMods ReShade section, or your own exported .ini. Ensure required shaders exist; this tool installs the standard packs from reshade-linux.sh only.

Uninstall manually (if ever needed)

• Delete/move ReShade.ini, ReShade_shaders/, and override dll (d3d9.dll or dxgi.dll) from the game directory, or use menu option 3 which backs them up.
