Mednafen

Mednafen (My Emulator Doesn't Need A Frickin' Excellent Name), formerly known as Nintencer, is an OpenGL and SDL multi-system free software wrapper that bundles various original and third-party emulation cores into a single package, and is driven by command-line input. It is distributed under the terms of the GPL-2.0-or-later license. Certain emulation cores of Mednafen have been ported to RetroArch/Libretro.

RetroArch's fork Beetle-PSX supports additional features, including hardware rendering (Vulkan and OpenGL), higher internal resolution, anti-aliasing, texture filtering, texture replacement, post-processing shaders, GTE subpixel precision and perspective-correct texture mapping.
