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.

[4] Certain emulation cores of Mednafen have been ported to RetroArch/Libretro.

[5] 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.

[6][7][8] The emulator runs under Microsoft Windows,[9] Linux,[9] AmigaOS, OpenBSD,[10] PlayStation 3,[11][12] RISC OS,[13] and Wii.

[14] There are a number of open-source graphical front-ends for Mednafen actively being developed.
