I need to give this one (the work-in-progress Sega Saturn core) a try but so far I haven't. Looks pretty darn good. I'm sure there is still a lot of work left but the progress made thus far looks very promising. I've been subscribed to the developer's patreon (<a href="https://discord.com/channels/647909397477195803/806644464834969640/1047355308210671666">Srg320</a>) for well over a year and I hope he is making a reasonable living from all of the work he has put in. He has made a number of impressive cores for the MiSTer FPGA. Big thanks to Video Game Esoterica putting the video together. He does good work too. Enjoy!
