    Latest - v1.2.2 (STABLE) Release Notes
    The PSP version has been usable for a long time but I think we should finally just release it as part of the new stable releases. Of course things are not going to be perfect but I hope just us going the extra mile and releasing this for a pretty much dead platform will mean something in and of itself to the people who use this platform.

    PSP is a pretty performance-hamstrung system so it requires plenty of edits and novel workarounds to make cores work fast enough on it. Right now we have cores like Gambatte working fullspeed and the PC Engine port also should be pretty impressive considering this is based on Mednafen PC Engine Fast, which should be far more compatible and accurate than something like Hugo.

    A sincere call to arms here for more PSP developers who want to be part of the effort: we have every intention of making as many ports run well on the PSP but the crucial thing here is that all of this costs work. If you are a capable PSP dev and you’d like to help out please let us know.

    V1.0.0.3 Beta Release Notes

    • More cores may be added in the future if they prove to be fast/stable enough to run on the PSP.
    • Bios files go into the cores/system directory.
    • For PSP slim/go, make sure you disable ISO cache, and enable high memory layout to allow access to the extra 32MB ram. (can be changed from your CFW menu ).
    • You bring up the retroarch main menu ingame with the "note" button, the one left of 'select'.

    This is a beta release so use it at your own risk

    Known issues:
    • Some cores require more than 32MB ram and will not work on psp-1000.
    • Cannot create saveram in tempGBA with some games.
    • nxEngine (cave story) takes too long to start.
    • Loading games from compressed files takes too long.
    • 'Restart RetroArch' option doesn't work.
    • Pressing left/right when in the menu can sometimes close it.
    • Most users reported blackscreen when running it on ps-vita (TN-V10).

    Resolved issues:

    • tempGBA now correctly saves sram to the correct folder (.sav extension)
    • Fixed an issue with tempGBA when loading compressed archives.
    • pce-fast: fixed most graphical glitches and improved speed a lot. most CD-rom games now run close to fullspeed.



    Additional information:

    • Main Menu can be accessed with the 'note' button.
    • Some cores require the following bios files present in the system directory ( default is RetroArch/cores/system) in order to run :

    libretro-CoreBios
    tempGBA

    • gba_bios.bin
    fmsx

    • MSX.ROM MSX2.ROM MSX2EXT.ROM MSX2P.ROM MSX2PEXT.ROM FMPAC.ROM DISK.ROM MSXDOS2.ROM PAINTER.ROM KANJI.ROM
    pce-fast

    • syscard3.pce ( required for PCE-CD emulation only)
    prboom

    • Requires prboom.wad in the same folder as the wad you want to load, you can get it here


    • You need to properly set your 'Extraction Directory' in 'Settings'-->'Path Options' to be able to load from compressed archives. .zip and .7z archives are supported.
    • FPS display is deliberately being forced to on in this debug build. it will be deactivated (and controlled from the main menu instead) in later builds.
    • This tempGBA build doesn't use frameskip, so expect framerate to sometimes drop below 60fps. this will hopefully be resolved in the future with either frameskip, or better, a custom hardware accelerated video renderer.
