We're happy to announce that Beetle PSX has been added to RetroArch Steam as core DLC!

Beetle PSX is a heavily modified fork of Mednafen's PSX module to the libretro API. It can be compiled in C++98 mode.

Notable additions in this fork are:

1. PBP and CHD file format support, developed by Zapeth
   
2. Software renderer internal resolution upscaling, implemented by simias
   
3. Vulkan and OpenGL renderers
   
4. High-resolution texture replacement
   
5. PGXP
   
6. Dynamic recompilers for increased performance
