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.

anyone got to test daxter, 3rd birthday and digimon world yet?

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



this is what i do for literally every core. and honestly, i wish retroarch wouldn't force you back into running gameplay while it reads or writes saves at all. just slows down gameplay and the writing process

Daxter works.

PPSSPP controls are weird, i try to move analog stick up and it acts as a dpad up and conflicts with movement

Disable digipad emulation for the stick, when you are playing a PSP game. Its just a setting in control settings.

PSP had both a digipad and an analog stick, so some games mapped both differently. In PPSSPP its the "double mapped". Simply disabling Analog stick digi pad emulation fixes this.

Takes maybe 4 seconds.

 

[EmulateLife]

Metal Gear ACID 2 and Metal Gear Solid Portable Ops both let you get in-game but there's no text on either one.

For ACID 2 that makes it impossible to play because there's options you must choose to advance. For Portable Ops it's just story you're missing.

LittleBigPlanet once you get in game you can hear the announcer talking but it's just a blue screen.

Assassin's Creed Bloodlines worked the first time I tried it. Now I get black screen before getting to start menu.

Resistance Retribution & Killzone Liberation skipping and laggy unplayable.

Working:
Daxter
Gran Turismo (maybe a tiny bit of slow down)
Dead to Rights Reckoning
Dissidia 012 Final Fantasy
Sonic Rivals (screen looks very bright, I had the same problem on PPSSPP on PC)
Sonic Rivals 2 (same as SR1)
Grand Theft Auto Chinatown Wars
Valkyria Chronicles II
Valkyria Chronicles III english patch

thank you, much appreciated. What does this mean "Video slowdowns are related to missing hardware accelerated decoding (nvdec)"
is there anything that can be done via settings to reduce the stutter in final fantasy crisis core cutscenes?

 

[bad361]

anybody knows why ssx on tour char model is fucked up even tho it runs pretty well on ir jit? any setting to try to solve it?

probably just some gl shenanigans

No.

Its literally ffmpeg running behind the scenes. So unless someone finds a more performant version of ffmpeg (KMFDManic of SNES Classic fame, might have, I remember he fixed a PPSSPP build for arm v7 and arm v8 that also stuttered before - and in the end also was 20+mb in size, so thats still ffmpeg at work - probably... But then, maybe its also using nvdec.) we wait for nvdec.

Behind the savestate issue probably _the_ most glaring issue for people trying to play games on it at the moment.

I unlocked all 41 Tekken 6 FMV endings. Didnt watch one of them (they can be watched later.. ). I know the pain.

I just wanted to say thank you m4xw. My weekend kinda dissappeared but it was so much fun! Now i am going to work and show the folks in the lunch room how i ball in gta vc!

 

[Deleted User]

Thank you for your hard work @m4xw!

 

[pohaxsf]

Now I can play PSP games on the go!

you already could

 

[Illuminaticy]

you already could

The joke





Your head

 

[Clydefrosch]

so i guess psp games were naturally locked to something like 30fps? is that why some games seem somewhat sluggish, even though activating fast forward seems to imply that there's still a lot of power going unused?
(and yes, I'm loading as instructed)

 

[Mambila2001]

Read the first posting..

Not sure if its in there at the moment, so I'll repeat the info snippet.

If you are on FAT32. (Please.)

Savestates work. There is a bug, where they dont finish loading.
You can circumvent that, by hitting load save state - and then switching into the retroarch menu again immediately, and staying in there until it has finished loading. Then they load.

Beta.

It hung when I pressed the "save state" button.

 

[notimp]

Unusual.

thankyou that was very informative

 

[SG911]

Read about this the other day! Seems promising, let's see how well it runs!

 

[Mambila2001]

Project Diva 2nd runs from 65 to 100% of it's speed while the switch is overclocked to 1785Mhz.

 

[spotanjo3]

I won't overclocked it at all. I will wait for him to improve it a lot. A core is only a beta. So it is a WIP. I will wait anyway. Great emulator for Switch, thought. No hurry for me.

 

[nWo]

That`s some great news!! Gotta save for a bigger SD card. Thank you man.

ahhhhh danganronpa/persona here i come
