## Running ## Running
To run this core, the "system directory" must be defined if running in RetroArch. 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. The Saturn BIOS must be placed there, $sysdir/{sega_101,mpr-17933}.bin 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.

## Condensing Games
Alternatively to using cue sheets with .bin/.iso files, you can convert your games to .pbp (Playstation Portable update file) to reduce file sizes and neaten up your game folder. If converting a multiple-disk game, all disks should be added to the same .bpb file, rather than making a .m3u file for them.
Most conversion tools will want a single .bin/.iso file for each disk. If your game uses multiple .bin files (tracks) per disk, you will have to mount the cue sheet to a virtual drive and re-burn the images onto a single track before conversion.
Note that RetroArch does not currently have .pbp database due to variability in users' conversion methods. All .pbp games will have to be added to playlists manually.
