The TurboGrafx emulator
This is Mednafen. It emulates TurboGrafx 16 and TurboGrafx CD games. I’ve configured Advanced Launcher to switch the SHIELD to 60Hz refresh rate if your TV supports it. So you should stick to NTSC (US) games to ensure perfect smooth scrolling.
Select: Select Start: Run NVIDIA: Toggle RetroArch menu
For TurboGrafx CD support you will need the CD BIOS file:
syscard3.pce
The BIOS file must be placed in the RetroArch system folder on the SHIELD:
Mednafen supports roms and cd images in the following formats:
- .pce
- .zip (zipped .pce files)
- .bin/.cue with support for .ogg audio tracks
For a quick guide to bin/cue files with compressed audio scroll to the bottom of this page.
You need to place the games in the pcengine rom folder on the SHIELD. You should name the files the way you want them to be listed in SPMC:
When you’ve added games to the pcengine folder you must do a scan of the folder in Advanced Launcher:
You are now ready to play TurboGrafx 16 and TurboGrafx CD games!
TurboGrafx CD games with compressed audio
The reasoning behind using compressed audio is to save space without any detectable loss of quality. As an example, Lemmings CD takes up about 450MB in regular bin/cue format. If you compress the audio files it only takes up about 55MB. The process is fairly technical though, so if you don’t care about the extra disk space then don’t bother with it.
You need to do the following:
- Use a CD ripper to rip the data track and audio tracks from the bin/cue
- Compress the audio tracks into .ogg format (.mp3 is not supported)
- Update the cue file to use the compressed audio files
There are guides for how to do this if you Google it, so I won’t go into details with that here. I’ll provide this example of the .cue file for Lemmings CD for inspiration:

If you are using compressed audio files you usually end up with 10 or more files for just one game. You can place the files in a subfolder in the pcengine folder instead of mixing them with regular TurboGrafx 16 roms:
