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.

Hi!
I open the Retroarch via album and my backups of psp doesn't work.
I did:
1- Load core and choose PPSSPP.
2- Load content and select the game.

How should I open it instead?

or, if you're at atmos 0.8.6 hold R while opening any game, it will bring up the Homebrew channel, so open the retroarch and you will be fine.

I'll check it out, thanks buddy!

These only run good with JIT, so you will need to be a bit more patient.

Is that also the case for the Burnout games?
The menus work fine but as soon as you try to start a race/go ingame it crashes.
It just shows a dark blue screen when I try to start a race.

Power Stone Collection and Ridge Racer run really well. Resolution at 1440x816

Can games be compressed to save space, or should they remain in .iso format?

Use CSO

I'm the process of testing a few games and most work fine however even after adding the assets i've come across a few with problems.

1.metal gear solid portable ops - shows no text after the press start screen i.e no new game, load game etc
2.metal gear acid 1- shows no graphics at all just colored boxes
3.Dragonball z tenkaichi tag team - loads perfect until you enter a vs fight and its just a black screen with audio.

many thanks.

Looking forward to test this, anyone tried any GTA games yet?

I get about 20fps in Vice City Stories with max Overclock.

 

[Paulsar99]

How's tekken 6?

 

[Purple_Shyguy]

Woah. Portable Ops and monster hunter without claw camera grip?! Very Nice.

Thank you so much for this! PSP Emulation was the one thing I wanted the most. A quick result with a few games I tested (1x Res, CPU 1.7GHz OC):

Burnout Legends - Game either crashes or blackscreens during car select. (I still have sound when blackscreens occur)
Persona 3 Portable - Stable 30 FPS
WipEout Pure - 30-40 FPS
WipEout Pulse - 30-35 FPS

I will test some more games later today or tomorrow and if everyting else fails, I can still enjoy P3P until we get a proper JIT.

Please, at least read the first post man...

Sorry, I figured out later. I was so nervous... (By the way, I'm a woman, not a man ).
Now It works, but in some games the diagonals doesn't work properly, like Dissidia 012 or Ape Escape P (the character walk instead of run).

Use iso not pbp - just reconverted all my roms. pbp introduces micro stutter.

Tekken 6 on IR Jit is no fun.
Tekken 6 on Jit (currently work in progress ) with GPU OC to to 460 Mhz and CPU OC to 1500 Mhz is pretty much full speed - and fun.

Same story for all the GTAs I'm afraid.

Playable with IR-Jit:

FF7 Crisis Core (runs pretty great, even at 3x resolution)
Persona 3 (for future reference, runs on jit as well (currently savestate reloading))
Persona 1

Thats about it..

In Lumines 2 some stages are playable, some are not... Lumines 1 stutters MUCH.

If you come across other games that run well on IR-Jit at the moment, list them. Its more a case of "most will not..." - wait for Jit.

Would you say persona 3 runs fine?
