    Just found this video uploaded yesterday of Leonidas87 running a WIP PS1 emulator on the Switch. Apparently it just needs a few tweaks to sound and speed before it's first public release!



    Massive thanks to m4xw for coding it and Leonidas87 for making this video!!

    Well I coded it, still takes some work.

    Audio doesn't work. Just got it somewhat stable.

    Right? I'm so pumped. PS1 is the #1 console I'm looking forward to emulating on the Switch. N64 a close second!

    Actually I think about dropping the core, as there are better cores for arm avaiable.

    Anyway it reports to me 60 fps, but the game feels slower than it should be.

    Surprised how good it runs for no GPU support

    Code:
    [libretro INFO] [Mednafen PSX]: Estimated FPS: 59.83407
    [Threading]: Waiting for Thread Exit
    [INFO] Threaded video stats: Frames pushed: 6345, Frames dropped: 2360.
    These estimates can be off by a lot, first level of crash bandicoot

    Wow it runs this smooth not utilizing the GPU? That is crazy.

    Great job so far dude I think you should keep at it! Looks awesome so far would love to be playing PS1 on switch some day soon!

    Well, it does feel slowed down, but gfx seem fine, but theres ghosting.

    Not sure if its just the games, or how the core just renders it

    Whats going on with the unloading of the map at the edge of the screen? I assume that's an on-engine issue to to being forced so wide, never intended to be that wide.

    If you do end up dropping this Beetle PSX core would you attempt PCSXrearmed? It would be good to see how much better it performs.

    You were never supposed to see that from the developer point of view

    Thats the plan. Anyway I think this core CAN be useful, but depending on the amount of work needed, I rather fix up retroarch

    Beetle PSX is definitely the better core accuracy wise but PCSX would be great to have in the short term for the quick speed boost. But your right, best to get Retroarch more stable first :)
