# Beetle PSX libretro

Beetle PSX is a port/fork of Mednafen's PSX module to the libretro API. It can be compiled in C++98 mode, excluding the Vulkan renderer, which is written in C++11 for the time being. Beetle PSX currently runs on Linux, OSX and Windows.

Notable additions in this fork are:

* PBP and CHD file format support, developed by Zapeth;

* Software renderer internal resolution upscaling, implemented by simias;

* An OpenGL 3.3 renderer, developed by simias;

* A Vulkan renderer, developed by TinyTiger;

* PGXP perspective correct texturing and subpixel precision, developed by iCatButler;

## Building

Beetle PSX can be built with `make`. To build with hardware renderer support, run `make HAVE_HW=1`. `make clean` is required when switching between HW and non-HW builds.

## Coding Style

The preferred coding style for Beetle PSX is the libretro coding style. See: https://docs.libretro.com/development/coding-standards/. Preexisting Mednafen code and various subdirectories may adhere to different styles; in those instances the preexisting style is preferred.
