Mednafen is the first emulator to implement the work taken from the full cracking of the Saturn. https://www.engadget.com/2016/07/12/...ction-cracked/
It will still be in development, but you can already tell that some games that never ran correctly, or at all before, run well on the latest mednafen. In my tests, you need a fast PC to run 3d games at full speed, something like a core i7 3.4GHz.
