Based on recent version of mupen64plus hg (~2.0 rc2) and patches I originally made for mednafen-ps3. Uses video plugins pulled from https://github.com/paulscode/mupen64plus-ae

To enable a dynarec CPU core you must pass the WITH_DYNAREC value to make:

• make WITH_DYNAREC=x86
• make WITH_DYNAREC=x86_64
• make WITH_DYNAREC=arm

TODO:

• Make sure all filesystem access targets directories a libretro core would be expected to access
• Make core options for important settings (a depth bias setting is badly needed)
