Here is Reaper’s second release using the MESS source code ported by ice88, it’s an Atari Lynx single system emulator. According to Reaper, Rygar is running at a playable 36FPS, although speeds for other games may vary & due to the PC MESS Lynx driver being incomplete, not all games will run & some might have glitches.

You can find the DC Atari Lynx M.E.S.S download which includes instructions on how to get it working at IMR Technology or you can grab the zip from here. If you have gotten other games besides Rygar to work on the emulator, you can leave some feedback about it in this forum topic.
