    Unifideck

    Unifideck

    A Decky Loader plugin that brings together games

    Unifideck is a Decky Loader plugin designed to unify a user’s game collection across multiple storefronts into one cohesive library experience on the Steam Deck. Instead of navigating separate lists for Steam, Epic Games Store, GOG, and Amazon games, Unifideck aggregates all titles into a single interface, making it easier to browse, launch, and manage games regardless of origin. It integrates deeply with the Decky Loader ecosystem, respecting existing plugin conventions and workflows while adding its own tools for library discovery and synchronization. The plugin aims to streamline the handheld gaming experience by reducing friction and redundancy when dealing with games installed or associated with different services. Unifideck also includes configuration options to tailor how games are displayed, filters to categorize titles, and compatibility handling to make mixed libraries feel native on the Steam Deck.

    Tiler

    Tiler

    Build images with images

    Tiler is an open-source tool that creates complex images by assembling many smaller images or shapes into a mosaic-style composition. Unlike traditional mosaic generators that rely on simple square grids, Tiler supports tiles with multiple shapes and sizes, allowing far more creative and flexible visual patterns. The software analyzes a target image and reconstructs it using a collection of smaller tile images or shapes that collectively approximate the original picture. This approach enables the creation of artistic mosaics built from objects such as circles, lines, letters, LEGO-style blocks, or other custom shapes. Because tiles can vary in form and arrangement, the resulting compositions can resemble handcrafted artwork rather than rigid pixel grids. Tiler is commonly used for creative visualization projects, digital art, and experimental image processing workflows.

    SDL_GameControllerDB

    SDL_GameControllerDB

    A community sourced database of game controller mappings

    SDL_GameControllerDB is a community-maintained database of game controller mappings designed to be used with the SDL (Simple DirectMedia Layer) library’s Game Controller API for both SDL2 and SDL3. Because many controllers report different axes and button layouts depending on platform and manufacturer, this project provides a large text database (gamecontrollerdb.txt) that maps those raw inputs to a standardized layout for consistent use in games and applications across Windows, macOS, Linux, Android, and other SDL-supported systems. Developers simply include or load the database file at runtime and call SDL’s API to add mappings, which enables out-of-the-box support for controllers that would otherwise behave unpredictably. The repository encourages community contributions so new or uncommon controllers can be added as they’re discovered and tested.

    NeuralScreen

    NeuralScreen

    DLSS 5 NR on your whole Windows desktop, in real time with Boost

    NeuralScreen applies NVIDIA DLSS neural rendering to the Windows desktop through a real-time graphical overlay. It processes games, videos, photographs, and other on-screen content without requiring individual application integration. Users can enhance the entire display or select a particular window for processing. Customizable rendering profiles adjust enhancement strength, color, and camera effects. Boost Mode reduces processing resolution to improve performance while preserving the final display resolution. Supported GPUs can also use DLSS Frame Generation, although compatibility varies by RTX generation. A comparison slider reveals differences between processed and original images. The application includes screenshots, audio recording, OBS integration through Spout2, and customizable keyboard shortcuts.

    DLSS 5 Autopilot

    DLSS 5 Autopilot

    Neural rendering into games that never shipped it

    DLSS 5 Autopilot automates the installation and management of community-developed NVIDIA neural rendering integrations for Windows games. It scans libraries from Steam, Epic Games, GOG, and other launchers to discover installed titles. The application examines game executables and graphics APIs to recommend compatible integration methods. It downloads required components directly from their original publishers rather than bundling third-party binaries. Users can update existing DLSS Super Resolution, Ray Reconstruction, and Frame Generation components where supported. Diagnostic tools inspect logs and crash reports to evaluate whether an integration worked. Preview and backup functions help users understand changes and restore original game files. Compatibility depends on the game, graphics hardware, drivers, and selected integration method.
