If you want to play your favorite Sega Saturn games on your PC, Mednaffe is the perfect emulator to help you do it. It's easy to use and has a variety of features, including screenshot and recording functionality. This lightweight, user-friendly version of the veteran Mednafen emulator ships with a media player and in-built Netplay, so you can play games on your PC no matter where you are.
The program is available for both Windows and macOS. The Mac version includes an external front-end GUI, which allows you to customize the interface. This GUI is similar to Mednaffe, but it's far more customizable. You can assign multiple physical buttons to different virtual actions and buttons. In addition, you can rewind your games in real-time. You can also save screenshots to.PNG files. It's a versatile emulator.
Despite its popularity, the main downside of Mednaffe is its size. This emulator is quite large, so you should have a lot of free space on your hard drive. If you're going to play the game on a laptop, you may want to download the 64-bit version. The 32-bit version won't run on your system. Depending on your system's hardware and graphics card, you'll probably want to use the 64-bit version. Otherwise, you'll have a smaller screen.
Another option is MedGui Reborn. This is a graphical frontend for the Mednafen multi emulator. The program is written in Microsoft Visual Studio Community, and comes with an appendix called MetroMed. With the latter, you'll have a modern "metro"-style interface to control the emulator. It's best to download a version of MedGui, so you can test it out before downloading the full version.
