I found the Atari800 CORE… atari800_libretro.dll, I really want to avoid MESS if I could, I have heard nothing but problems with 5200 games…
And the link here…

Dropped it into RetroArches CORE folder, went into RetrArch, Load Core and it shows Atari800 3.1.0
Is there any docs how to set this up with RetroArch and does it need the bios ?
If it NEEDs the bios how do you set it up so I can run 5200 games (a52 or bin files)
