Mednafen Emulator Setup:
Once you have Mednafen installed you need to go into your installation folder, right click on the mednafen.ctg file and open it up in a program like notepad and make some changes. Note: you can also download and drag a custom visual interface called Mednaffe into your installation folder found at the bottom of this guide. Which might be an easier alternative, but be sure to check out the Hotkey commands further down for setting up the inputs for the controller further down as well. Otherwise, use Ctr+f within the mednafen.ctg document to search for what you need as shown below:
Recommended Settings:
- Within the mednafen.cfg, file and using notepad or notepad++ to edit it, make these changes and save:
Video Settings:
-Hit ctrl+f, search for: ss.stretch change ss.stretch aspect_mult2 to ss.stretch aspect
-Hit ctrl+f search for: ss.correct_aspect 0 is native 1 will squash or stretch to 4:3
-Hit ctrl+f search for: ss.videoip 0 will give you sharp pixels 1 will apply bilinear filtering (a blur)
Other Settings:
-Hit ctrl+f search for: video.frameskip set this to 0 so the emulator renders all frames
-Hit ctrl+f search for: ss.scsp.resamp_quality sound quality for the scsp 0 is lowest 10 is highest default is 4
-Hit ctrl+f search for: ss.midsync setting to 1 can reduce input lag but increases CPU load
-Hit ctrl+f search for: cd.image_memcache if you have a good bit of RAM setting this to 1 will load the entire game into your RAM
Mednafen Emulator Hotkey Commands:
Alt + Shift + 1 -> Set controls for Player 1 Alt + Shift + 2 -> Set controls for Player 2 Alt + Enter -> Full Screen 0 - Save Screen Snapshot F5 - Save Game State F7 - Load Game State F11 - Toggle FPS Text ctrl+shift+esc (only use this if you have to force close Mednafen)
Loading a game:
Before loading a game make sure your game files including the .cue and .bin files are together in one folder. To start a game drag an .cue file of your chosen Saturn game over the mednafen.exe file found in your main directory folder. For multiple disc games you will have to make an m3u file (see the RetroArch section above called "Visual Guide"). Once you do this load that m3u file by dragging it into the Mednafen .exe to start the game. When you have to switch discs do the following: F8 to open/close tray F6 to switch between discs
Add the Mednafen Interface (Mednaffe) to your installation folder: An alternative to manually setting up the emulator using mednafen.ctg is to download and use Mednaffe in your Mednafen installation folder. Just download the interface and drag the files into your installation folder. Click on the Mednaffe.exe to bring up the interface. From here you can load a game, change inputs, video and sound settings. A much easier way to manage your settings. You can find the Mednaffe inteface here: https://github.com/AmatCoder/mednaffe
