Beetle PSX libretro

This is fork of Mednafen PSX. It has been ported to the libretro API. It currently runs on Linux, OSX and possibly Windows.

Running

To run this core, the "system directory" must be defined if running in RetroArch. The PSX BIOS must be placed there, $sysdir/SCPH550{0,1,2} for Japanese, NA and EU regions respectively.

Memory cards will be saved to "save directory", memory card #1 is saved using libretro's standard interface. The rest of memory cards are saved using Mednafen's starndard mechanism. You might have to rename your old memory cards to gamename.srm. Alternatively you may just rename it from gamename.gamenamehash.0.mcr to gamename.gamenamehash.1.mcr and load them off the corresponding slot.

Core now supports save states. Keep in mind states might result on loss your memorycards if you are careless.

Loading ISOs

Beetle differs from other PS1 emulators in that it needs a cue-sheets that points to an image file, usually an .iso/.bin file. If you have e.g. foo.iso, you should create a foo.cue, and fill this in:

FILE "foo.iso" BINARY
   TRACK 01 MODE1/2352
      INDEX 01 00:00:00

After that, you can load the foo.cue file as a ROM. Note that this is a dirty hack and will not work on all games. Ideally, make sure to use rips that have cue-sheets.
