Mednafen PSX (Beetle PSX) is a Sony PlayStation1 video game system emulator
that can be used as a libretro core. It is a libretro port of Mednafen
PlayStation.
Mednafen-PSX requires the following BIOS image files for operation:
* scph5500.bin (MD5 sum: 8dd7d5296a650fac7319bce665a6a53c) NTSC-J
* scph5501.bin (MD5 sum: 490f666e1afb15b7362b406ed1cea246) NTSC-U
* scph5502.bin (MD5 sum: 32736f17079d0b2b7024407c39bd3050) PAL
The bios names are case sensitive.
The scph7003.bin BIOS image is the same as scph5501.bin, but will need to be
renamed to scph5501.bin to be used.
Mednafen can load CD-ROM games from a ripped/dumped copy of the disc such as
CUE+BIN, CloneCD "CCD/IMG/SUB" rips and cdrdao "TOC" files. For games with more
than one CD create a M3U file(plain-text, ".m3u" extension) and enter the
filenames of the CUE/TOC/CCD files.
Beetle PSX can use an OpenGL or Vulkan renderer instead of the accurate software
renderer. This will require support in the libretro frontend, video card and driver.
To switch between OpenGL and Vulkan renderers configure the video driver in
RetroArch. This can be done in the menu at 'Settings > Drivers > Video Driver'.
To build the OpenGL renderer use:
OPENGL=1 ./beetle-psx-libretro.SlackBuild
To build the Vulkan renderer use:
VULKAN=1 ./beetle-psx-libretro.SlackBuild
To build both the OpenGL and Vulkan renderers use:
HW=1 ./beetle-psx-libretro.SlackBuild
To build the debugging symbols use:
DEBUG=1 ./beetle-psx-libretro.SlackBuild
