PPSSPP/Libretro Switch Public Beta by m4xw
==========================================

After a lot of work, I am very happy to share this with all of you.
Audio & Video support works, many core options cause Issues tho.

It is mandatory to "Close Content" after changing any Core option and restarting RetroArch, else it will potentially crash, don't close the RetroArch menu!

Special thanks to hrydgard for everything he has done for the PPSSPP Project.
If you want to support his work, consider buying PPSSPP Gold https://central.ppsspp.org/buygold even if you don't use it!

I will PR it once the libretro port is finished, also implemented half of what's needed for a Standalone port
Source is on my Github, but it's highly WIP and needs a custom RA and a custom ffmpeg, so you should just wait if you want to build it yourself

GitHub (WIP Switch): https://github.com/m4xw/ppsspp/
GitHub (Official): https://github.com/hrydgard/ppsspp

Installation Instructions
==========================================

Drag & Drop the "retroarch" folder to the root of your SD, overwriting any file (it will not touch any options).
Assets are bundled, so you don't have to bother with that.

Notes
==========================================

If you are using ANY method of loading RetroArch OTHER than Atmosphere's title redirection feature, DO NOT report issues that you encounter.
These issues can skew testing and could very well be caused by loading through an unsupported method.

Video slowdowns are related to missing hardware accelerated decoding (nvdec), it's not a libretro/PPSSPP Issue.
FMV cut-scenes will be fine.

Updates
==========================================

Added JIT and JIT Vertex Decoder Support
- When loading Savestates with JIT, make sure to instantly open the RetroArch Menu again and wait for it to complete loading
- This is a libretro specific bug (not switch port related) and will be fixed later on

==========================================

-Added Vertex JIT Core option (turning it off fixes some games currently)
-Added Disable slow Framebuffer effects Core option (Speedhack)
-Increased Savestate Chunk size to 4MB (speeds up savestate load, ~2sec)
-Band-Aid for Savestate load + Save (no more opening menu for them to work)
-Renamed "IR JIT" to "IR Interpreter"
-Removed Threaded IO Core option (non-functional)
-Removed Non-Buffered Rendering Core option (non-functional)
-General system stability improvements to enhance the user's experience.

i can take care of setup just need info on how you booting to hb. I think you are doing what we did on ps4 and making an iso right?

Nah no need to create an ISO, you just boot the HB's Eboot.pbp like normal
I have my PSP homebrew in a PSP folder in the root fo my SD. For some reason PPSSPP doesn't like it when the HB in a long Directory, so keep it short then you shouldn't have any problems.
There are a few PSP HB that work on the standalone PPSSPP Emulator that doesn't on our PPSSPP but overall the Compat is really high.

Oh and OpenMugen DOES boot! but there is only the default character and no stage background/music

Killzone works ok (maybe a tad bit slow still but ok) if you turn off the vertex cache (Speedhack).

Since you don't want that setting to be off on all games turn it off then save game option file at the top of options, then close content, and restart the game.

If a game doesn't work try this with either or both of the speedhacks to see if it fixes it.

what if game works but stutter every 4 seconds like both GTA games. also do you know what settings made killzone work,the game will not boot at all.

by the way i have tested this on both sx os & atmosphere with full ram access

Content ID issues with the videos above solved.

is it possible to remap the right buttons to the right analog stick so you can play a game like super star dust with both left & right analog sticks ?

--------------------- MERGED ---------------------------

(although pbp and cso also should work))

isn't pbp only for ps1 eboot games ?

I just told you in the post you quoted turn off vertex cache (speedhack)

Yes, the part where I write about that once you have a remapping file loading, you can change the button config in settings (controller something, browse around, you'll find it. ) was meant to tell you that.

Killzone works ok (maybe a tad bit slow still but ok) if you turn off the vertex cache (Speedhack).

wait.. kill zone works? how come in my case the game is semi frozen starting the language selection screen, where it takes a few seconds to draw each frame? I tried JIT and IR JIT, both speed hacks disabled, all the same.

Gran Turismo is doing the same thing for me, the main menu (8 icons) is extremely slow. And so is midnight LA remixed, driving in town is fine but once a message comes in the frame rate became single digit. Is there any option governing those 2D elements that I'm setting wrong?

I attached some PSP remap files in the RetroArch thread, Monster Hunter Frontier one would make the trick

i did it.thanks but it's not working because when i play the game using both sticks when i fire using the right stick the ship stalls until i let go of the right analog stick !! maybe i did something wrong !! is there any easy way i can reset the controls to original settings so i can start over ?

 

[notimp]

The game remap file you've set up should be the place where those remaps are stored, just delete it and start over.

Also by default the analogstick is mapped to analogstick and digipad - for PSP this is a bad idea, so uncheck digipad emulated by analog stick for controller 1 - maybe thats related to your issue.

 

[satel]

I just told you in the post you quoted turn off vertex cache (speedhack)

made absolutely no difference,i think these stutters are here to stay because i have tried every single setting without any luck. you can play the game if you don't speed in cars but this also means you cannot play the levels with racing missions or retroarch will freeze. shame

--------------------- MERGED ---------------------------

edit: Just saw that Killzone is now reported working as well.

who reported it working ? or are you talking about a new unreleased PPSSPP core update !!??

latest released jit core = retroarch crashes at the language selection screen in killzone

ok i will try this later. thanks

Fixed linker errors with FFMPEG + NEON optimizations, video playback should be a lot better in a future build.
Also shaved off some binary size, added JIT Vertex Decoding as Core option, which will fix some games (for now).
Currently in testing...

This is also interesting for @cpasjuste , assume you don't use neon optimizations yet? Might improve pplay by quite a lot.

https://github.com/m4xw/ppsspp-ffmpeg
Just hit ./switch.sh, but it uses a older ffmpeg ver, dunno if your code is compatible.

I was helping you with Killzone, nothing else. I don't play those GTA games on PSP I have them on PS2.

Yep, very interesting. I'm off for a few days but I'll give a look as soon as I come back. Thanks.

You might want to enable some codecs/avdevice whatever but u know that.
Else its a very simple rebase.

Awesome emulator.
All the Loco Rocos work great.

on what setting does your Killzone run well? JIT? both speed hacks off? What about other settings? Mine loads but pretty much freezes (0.1fps) at language selection.

I'm not trying to be rude but I feel like people can't read. Why do I need to repeat for the third time turn off Vertex Cache (Speedhack). It doesn't work perfect but it works it's a litle slow. That is the only setting I changed.
