To configure Mednafen, you need to edit the mednafen.cfg file. You can use any text editor to do this. The configuration file is well-documented, so you can easily find the settings you need to change.

You can create a per-module configuration file by creating a file with the same name as the ROM file and placing it in the same directory as the ROM file.

Overall, configuring Mednafen is a straightforward process. Once you have edited the mednafen.cfg file and set the appropriate settings for your input devices, video, and audio, you should be able to start playing your favorite games with ease.

Loading and Playing Games

Now that you have successfully installed Mednafen, you are ready to load and play your favorite games. To do this, you will need ROM files of the games you want to play. You can find ROM files online, but make sure you only download them from reputable sources.

Once you have obtained your ROM files, save them to a folder on your computer. Launch Mednafen and select the system you want to play on from the list of supported systems. Click on the “Load Game” button and navigate to the folder where you saved your ROM files. Select the ROM file you want to play and click “Open”.

If you have compressed ROM files, Mednafen supports a variety of compressed file formats such as ZIP, RAR, and 7Z. Simply load the compressed file and Mednafen will automatically extract the ROM file.

If you want to play CD-based games, Mednafen supports CD emulation. You will need to create an image file of the game CD using software such as ImgBurn or Alcohol 120%. Save the image file to your computer and load it in Mednafen by clicking on the “Load CD Image” button. Mednafen also supports multiple-CD games, so you can switch between discs as needed.

In summary, loading and playing games on Mednafen is a simple process. Just make sure you have ROM files or CD image files of the games you want to play, and Mednafen will take care of the rest.

Using Save States

Save states are a convenient way to save your progress in a game and pick up where you left off later. In Mednafen, you can save and load save states using keyboard shortcuts.

To save a state, press the F5 key. This will save the current state of the game to a slot. You can have up to 10 save state slots per game. To load a state, press the F7 key. This will load the last saved state.

You can also load a specific state slot by pressing the F8 key. This will bring up a menu where you can select the slot you want to load. Alternatively, you can use the command line to specify the slot number when launching Mednafen.

It’s important to note that save states are not the same as in-game saves. In-game saves are created by the game itself and are stored in the game’s save file. Save states, on the other hand, are created by the emulator and are stored separately from the game’s save file. This means that if you delete the save file, your in-game saves will be lost, but your save states will still be available.

Save states can also be useful for debugging purposes. If you encounter a bug or glitch in a game, you can save the state and then try to reproduce the issue. This can help you identify the cause of the problem and find a solution.

Overall, save states are a powerful tool that can help you enjoy your favorite games without worrying about losing your progress. By using the keyboard shortcuts and command line options, you can easily save and load your progress in Mednafen.

Taking Screenshots

Mednafen allows you to capture screenshots of your gameplay easily. To take a screenshot, press the F8 key. The screenshot will be saved in the same directory as your game ROMs. You can also change the screenshot directory by editing the screenshot_directory setting in your Mednafen configuration file.

If you want to take multiple screenshots, you can use the screenshot_interval setting to automatically take screenshots at a specified interval. For example, if you set screenshot_interval to 60, Mednafen will take a screenshot every 60 seconds.

You can also customize the format of your screenshots using the screenshot_format setting. By default, Mednafen saves screenshots in the BMP format, but you can change this to JPEG or PNG if you prefer. Note that changing the format may affect the quality and file size of your screenshots.

To view your screenshots, you can use any image viewer that supports the file format of your screenshots. You can also use Mednafen’s built-in screenshot viewer by pressing the F9 key. This will open a dialog box where you can browse and view your screenshots.

Overall, taking screenshots in Mednafen is a simple and straightforward process. With just a few key presses, you can capture and save your favorite gaming moments to share with others.
