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

Libretro Docs (important informations for this core): https://docs.libretro.com/library/ppsspp/
Official Game Compatibility Tracker (your mileage might vary): https://report.ppsspp.org/games

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.

No, not that I'm aware of. I don't think the Switch would be capable of emulating two PSPs at the same time. If you have Retroarch, you can emulate two GameBoys at the same time to play multiplayer that way though

Would I be able to use this to play LCS and Vice City Stories and have access to the old school GTA cheat devices in them via this emulator? That would be awesome to have access to again without having to dig out my PSP. The switch is everything I hoped the Vita would be.

Also that's really cool to know about emulating 2 gameboys if I ever find a use for it.

You can play GTAs only in PPSSPP standalone GLES ver with a bit of OC (you can also apply some cheats like 60 fps mod or camera mod). Its not completely stutter free, but i'd say its very playable. In RA PPSSPP its pretty much unplayable due to its stuttering too much. But if you want the best psp GTA experience, i assume lakka is the way to go (or even android).

 

[Lunatics]

Thanks, apreciate the info. As far as cheats go I was thinking of the old original cheat devices for PSP that were essentially a modified save or something you would load which gave you all sorts of crazy cheats from a menu in game. Spawn vehicles and objects etc etc. The LCS one is how you would originally hack your PSP and load homebrew was through the GTA save file.

Hey anyone tried playing Daxter? It has been running PERFECTLY on the highest settings until I got to this area where you fly a bike around and spray bugs on plants and fps dropped significantly, afterwords it was back to perfect 30fps. Since then I run in and out of situations of lower fps and it ran better when docked but still noticeable lag. I just wonder if it could be any type of compatibility thing or if it's just not enough power, i'd love to overclock but I don't think cys-clk would work for ppsspp. I use ppsspp installed with tinfoil vs whatever the retroarch version is, I have no idea how to do the retroarch version.

sys clk gui would certainly work. You would have to make either a forwarder for ppsspp or the iso itself. But yeah methinks oc would fix those troubles.

Does this work well with birth by sleep?

Will try to get it working, thanks for the reply!

Has anyone been able to play Final Fantasy Tactics without the audio popping???? I have the CPU and GPU both max OC.

 

[Purple_Shyguy]

I have a psp save. How do I load this up via emulator?

I copied the save folder to SAVEDATA but I get nothing in game. No way to load.

Then your save is for different region probably, cause everything works fine for me when importing saves. Get the right save for your specific region ver. of the game or you could trying to convert the existing one with some software iirc.

 

[Deleted User]

does anyone have a pre-made cheats file to use in Retroarch psp core?

tried copying my psp cheats to switch, but i think i need to convert them or something, i have no idea how to use them and Retroarch Documentation isnt clear for me

if someone manage to use cheats, please share your file

Google war of the lions slowdown patch

 

[bebo2019]

is there any update to work with 9.x firmware and higher

 

[bad361]

Huh? I'm on 9.1 and everything works just fine.

 

[Natural]

I was using Lakka but I guess I'll use this instead. I can't even save my game data in Birth By Sleep with Lakka.

 

[Yuubah]

I tried ff7 crisis core today, but it crashes retroarch everytime i try to save game.

i reinstalled fresh copy of retroarch from the retroarch website, not in applet mode. any idea what i'm doing wrong?

 

[guywhatever]

Google war of the lions slowdown patch

I already have that patch applied to the game. That isn't the issue here at all... And the fact that the audio pops and crackles is horrible as well.

Hmm plays just fine for me, so I'm trying to figure out what it could be. I'm on stock clock, but just in case use sys-clk and bring your clock up to 1581. Also, I'm sure you already are, but make sure you're using override method and not applet mode

Yep, using override method and already OCing the CPU. Guess I can stick to playin it on the vita, but it doesn't make sense if it runs just fine for others and not so much for some.
