5. Understanding and Using Shaders
Shaders are programs that apply visual effects to the emulated output, enhancing the graphics. They can simulate the look of CRT televisions, apply smoothing filters, or add other visual enhancements.
* Where to Find Shaders: Shaders are typically located in the `shaders` directory within your RetroArch installation folder.
* Applying Shaders:
* Load a game.
* Open the Quick Menu (usually by pressing F1 or the Guide button on your controller).
* Go to `Shaders` -> `Load Shader Preset`.
* Navigate to the `shaders` directory and choose a shader preset (.glslp or .slangp file).
* Common shader presets include:
* crt-royale.glslp/slangp: Simulates the look of a high-end CRT television.
* crt-geom.glslp/slangp: Another popular CRT shader.
* easymode.glslp/slangp: A simple smoothing filter.
* scalefx.glslp/slangp: A scaling algorithm that preserves sharpness.
* Shader Passes: Many shader presets consist of multiple passes, allowing for complex effects. You can adjust the parameters of each pass in the Shader Parameters menu.
* Performance Considerations: Shaders can be demanding on your hardware. If you experience performance issues, try using simpler shaders or lowering the resolution.
6. Scanning for Games and Creating Playlists
RetroArch can automatically scan your ROM directories and create playlists, making it easy to find and launch your games.
* Organize Your ROMs: Before scanning, make sure your ROMs are organized into separate directories for each system (e.g., `NES`, `SNES`, `Genesis`).
* Scanning Directories:
* Go to `Import Content` -> `Scan Directory`.
* Navigate to the directory containing your ROMs for a specific system and select `Scan Directory`.
* RetroArch will scan the directory and identify the games. If the game is in the database, it will automatically add the correct box art.
* Manual Scan: If the automatic scan fails to identify a game, you can use the “Manual Scan” option. This allows you to manually specify the system, core, and file extensions to use for scanning.
* Playlists: After scanning, RetroArch will create playlists for each system in the main menu. You can then browse your games by system and launch them directly from the playlist.
7. Save States and Rewind
Save states allow you to save your progress at any point in a game and load it later. Rewind lets you rewind gameplay to correct mistakes.
* Saving States:
* While in a game, open the Quick Menu (F1 or Guide button).
* Select `Save State`.
* RetroArch will save the current game state to a file.
* Loading States:
* Open the Quick Menu.
* Select `Load State`.
* RetroArch will load the saved game state.
* Rewind:
* Rewind is enabled by default but can be configured in `Settings -> Core`. You may need to increase the “Rewind Buffer Size” for longer rewind times.
