The description of Mednafen - Play With New Friends
Mednafen is a multi-system emulator that lets you emulate tons of different consoles and platforms. The list of supported systems includes: Apple II/II+, Atari Lynx, Neo Geo Pocket (Color), WonderSwan, GameBoy and GameBoy Color, GameBoy Advance, Nintendo Entertainment System, Super Nintendo Entertainment System/Super Famicom, Virtual Boy , PC Engine/TurboGrafx 16 (CD), SuperGrafx, PC-FX, Sega Game Gear, Sega Genesis/Megadrive, Sega Master System, Sega Saturn, and Sony PlayStation.
It's very important to keep in mind that Mednafen does not have an interface, per se. This emulator works via command line, so it might be a little strange at first for users who are accustomed to more conventional emulators. That said, using it is incredibly easy. All you have to do is drag the ROM of the game you want to play to the executable (which is, by default, called mednafen.exe). That's it! The only exception to this is for PSX games, in which case you'll need to save the BIOS to the firmware folder first.
Once you've started a game, press 'Alt+Shift+1' to set up the controls, which you can customize to your heart's content. To use an Xbox or Playstation controller, however, the process is a little more complicated. Luckily, on Mednafen's official website, you can find all the information and tutorials you need to set things up properly.
Mednafen is an excellent emulator. Its main strength is that with just 6 MB, it lets you emulate more than a dozen different systems, which means you can play thousands of games. In addition, there are several different front ends, so you can use whichever interface suits your needs.
