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

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.

Delete retroarch-core-options.cfg and voila.

As I said I've tried that.

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

In the end, completely reinstalling Retroarch and PPSSPP's core fixed it. Needless to say: don't mess with that setting!

Is there a compatibility list for psp games already? (with average FPS numbers)

I don't think it's necessary right now until dynarec core will be released.

Doesnt know how Retroarch works. Gives advice to others.

This setting is stored in core options, or game options .cfg files (if you have created an individual game configuration file, by clicking on "create individual game configuration file). Just because you dont know where to look for those cfg files, doesnt mean everyone else has to be especially careful.

No really, it doesnt.

Somehow I managed to turn on IO Threading and now I crash every time I try and use the core. I've even tried deleting my core and retroarch config files. I get:

Error:workerInit() failed. Press the + button to exit.

https://pastebin.com/cVJ7DeC3 - here is the crashlog

The crashlog just means that exit() is called.
But yea the option currently doesnt work.

I cant wait for this to support exfat and sxos officially.

The wait is so long lol..

Not in your lifetime.

Hi, how to set OC on GPU? I set CPU OC but no see GPU OC

I could be wrong, but I don't think that's a thing in RetroArch itself.

 

[Clydefrosch]

vsync off?

Its on, but when I turned up the swap interval von 1 to 2, it got so much better. Made the menu stutter though but that's an acceptable tradeoff
Thanks

edit: the setting does mess with some games like bust a move, that seemingly ran 60fps.

 

[notimp]

Currently you dont need GPU OC. On IR-Jit the benefits are none to very minimal (imho - only tested on Persona 2). In Jit they are larger - but Jit isnt in a releasable state yet.

FYI God of War Chains of Olympus will eventually run at playable speeds. Probably.

Heres a video of it at 1,5 GHz CPU OC and 460 MHz GPU OC, with the 30 fps patch - almost in fullspeed. This was captured on a frankencore (test build) that had parts jit and parts interpreter code running, that will probably ruin your savestates and eat your your switch alive - but still, its a fun glimps.

Don't take this as a state of how "done" JIT is, because this isnt even proper jit. Means nothing, is just fun to look at.

3x resolution.

 

[djluis49]

Does this work on Reinx?

 

[Brawl345]

Does this work on Reinx?

It works on EVERY CFW that has the JIT patches (so ReiNX and SX OS too).Theoretically. Just don't report issues when you don't use Atmosphère/Kosmos. Works fine here with SX OS.

 

[steven89]

how you skipped the intro from a black screen, what settings do you have the game setup on.

i ran into this issuse as well, to sort it i done an over clock and restarted retroarch loaded up my game sorted
now playing yu-gi-oh tag force

Heya!

Using atmosphere, last version, installed all step by step but whenever I launch my .iso it freezes the whole switch, any clue what can be the problem? Iso seems fine using PPSSPP on PC. Reformated the card to FAT32 since first tries were on exFAT, trying to boot crisis core at present.

My knowledge is quite limited, just begun only with Atmosphere and to add some New Threat mod on a fresh FF7 playthrough so please don't go super indepth on how to "fix" it

Regards!

hold R while starting any game on your switch (not album) and go to retroarch from there.

also, potentially you might have to put both the iso and retroarch on the sd card freshly, as files could have been corrupted during your exfat crashes.

Dope! all sorted, seems something went badly with exFAT, all working super good! Just trying to find how to access the core configuration while the game is loaded, is there a hotkey I need to press? (tried to find it across the thread but either I'm blind or everyone takes for granted it's basic knowledge)

I'm not sure what the default setting is, it might be l+r+minus+plus or clicking both sticks at the same time or holding plus?

otherwise, you need to go to input settings i think and set a hotkey before you load a game. personally, i use R3 for the menu.

also, check your installed games, if there was some corruption issue, a few of them might not be working anymore too

hey can you pm when you get a chance

Went for full reinstall, luckily didn't have much.

Minus and plus worked, so many thanks for that! Pretty sure all I asked had already been answered, so many thanks

Regards!

[xavier_cross31]

Tried with Valkyrie Profile Lenneth, and all I get after the joystick calibrating is a blank screen? any one tried that one yet?

 

[pinbi7]

Transfer my save file from PSP to Switch on Ridge Racer 2 much better with full screen than PSP 2000/3000 a/v plug in and it ran beautifully!
