PPSSPP Switch Beta Release

1.jpg

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.

Vulkan is only for the Lakka and Linux which you have to boot in to this thread is about PPSSPP on Horizon the main OS. Are you trying to run it on Horizon or Lakka?

If Horizon you need to hold down R on a switch game and access the homebrew menu that way to get the extra ram and then launch Retroarch from there.
Thank you for the quick reply. I use Hekate v4.10.1 to get to Atmosphere v0.9.1 which loads me into homebrew. Currently using RetroArch v1.7.6, and as i said before my 4 other cores work perfectly fine, and i have to hold down R to get to homebrew because of Atmosphere. So what would be the issue?

Im having an issue. PPSSPP core loads fine, followed instructions perfectly. But whenever i try to load a game i get an atmosphere error message each time. I have all the assests in the system folder and i have a gl video driver. Do i need Vulkan to run this emulator? If so how do i download it and add it to retroarch? Am a semi-noob and already proud i was able to get this far with my other emulators(GBA/GBC, DS, PS1). Help much appreciated!

Been having the same problem but fixed it with this. Link below. People seem to like to say how to do things without actually explaining where or how to get the information required.

Edit: In short, this tells you how to use the hold down 'R' trick when launching a game.

He already has Atmosphere so you didn't help him at all, and I said to hold R on a switch game it's not that complicated you just do exactly that. I don't know what your'e talking about.

And you said you did copy the assets over? Not sure then, you could try overclocking in Retroarch. Also make sure you're on the latest nightly of PPSSPP. Other than that IDK.

Thank you all so much i really appreciate it, as i feel like a dumbass now. I had always used albums to get into homebrew, loaded into Smash instead and it is working perfectly. Currently playing megaman and am so grateful to you all. Special thanks to the original Dev, youre awesome!

Already did but the flickering isn't the problem. As I said, it works properly in Dracula X Chronicles but in SoTN the game is slowed down when there's 3D elements

Have you tried overclocking in Retroarch? If that doesn't help it's probably just not going to work until a certain update were to fix it.

Yep, overclocked to the max
So yeah, I already tried to mess with the settings a little bit so I guess that I'll just have to wait for some updates

Just be aware that an update to PPSSPP for Retroarch Switch may or may not fix your problem. There's over 1000 PSP games out there and when the devs do an update it doesn't necessarily mean one certain game is going to work better. It may never be fixed.

How do you overclock ? Mine is written : 0 with a !
And i can't change it.

Thank you.

I would link a URL but this forum won't even let me post a chopped up non hyperlinked version of it until I have five posts. Anyway, google "switch retroarch nightly" (without quotes) and go to the first link. Hopefully your google has the same results as mine. That's the nightly build for switch retroarch. Overclocking broke in the stable release as of switch update 8.0.1 I think.

I'm pretty sure all you need is the nro in RetroArch_loader_update zip. Just replace your current RetroArch nro with that one, that's what I did and now I can overclock again. If you want to be safe then download one of the other zips and reinstall the whole thing.

Start a game go into settings and change it.

But any time you make any changes to the settings close content for it to take effect and not crash Retroarch. Then restart the game.

Probably a niche issue so I don't know if anyone would be able to help but I'm having issues running the translation patch of Makai Kingdom/Phantom Kingdom Portable. When I start a battle it goes black screen. It's the same ISO and save file I'm running without issue on my Vita, and other games are working just fine on the core, including Phantom Brave which is a very similar game made by the same devs. I'm guessing it's not the fact that it's translated, since I've been able to run some other translated games just fine including the latest Yu-Gi-Oh Tag Force

Hi:

I have read the entire thread but I haven't been able to find a solution for the problems I'm having:

- There are certain games such as MGS: Peace Walker and Sega Rally which don't display text at all in menus and saving stuff. I have downloaded the latest stable build from the libretro page (currently 1.7.7), I am running Retroarch with full memory from a forwarder in Horizon, and I have tried enabling/disabling the speed hacks and other options. What can I do?

- Besides, there are other games which are supposed to run well but I can't get to make them work. These are: Daxter (loads but when I try to start a new game I get a black screen); DBZ Shin Budokai (after the intro it gets frozen in loading; DBZ Shin Budokai Another Road (can't make it work at all); Metal Slug Antology (freezes after intro).

Thanks in advance.
