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.

Where on my SD card does peace walker install the extra data with this emulator?

 

[jamstripe]

30Fps cheat in Peace Walker makes the game run even slower.. anyone know how to get around this? Ok i think i found the problem, I had the 60fps and 30 fps cheats all in the same file. removing the 60fps one seems to have fixed it.

 

[cucholix]

what clock speed is your CPU? run it at the top two for peice walker to run fullspeed. Fullspeed for that game is 20fps. there are ways to get it to 30/60fps but ive not worked that out yet.

One step over the stock OC

 

[Blackforce]

After some more testing, these are my results (Still 1.7GHz OC, 1x Res):

Ace Combat X - Stable 30 FPS
Asphalt Urban GT2 - 20-25 FPS
Burnout Dominator - 20-28 FPS
Burnout Legends - Game either crashes or blackscreens during car select. (I still have sound when blackscreens occur)
GTA Vice City - 15-20 FPS
Hatsune Miku Project Diva 2nd - 25-28 FPS
Jeanne d'Arc - 22-25 FPS
Persona 3 Portable - Stable 30 FPS
Valkyria Chronicles 2 - Stable 30 FPS
Valkyria Chronicles 3 - Stable 30 FPS
WipEout Pure - 30-40 FPS
WipEout Pulse - 30-35 FPS

So, yeah. Racing games are not playable for the most part, but RPGs tend to seem fine. Also, fullspeed Ace Combat is a good thing.

PPSSPP is a great addition to the Switch. There are so many games I wanted to play but never got around to it on PSP. But how with a PSP emulator on a dope ass piece of hardware, there are so many good things about this.

well you need to go a step or 2 more

 

[pohaxsf]

Will this ever be compatible with SXOS down the line?

Since I am running that on 7.0.1. I cannot play any PSP games right now as it constantly crashes for me.

press r when launching a game

 

[spotanjo3]

not accurate list,age of zombies freezes in the middle of the 1st level & atari evolved feels like it's running at 2fps, the list says these 2 games run PERFECT

Yeah, Found out that it was for PC/macOS and maybe Vita.. Not Switch, I think.

 

[chocoboss]

There is no PPSSPP for vita it feature it own psp emu ...

Hey. When i launch a game and will set the resolution in options, retroarch is crashing. Why

When you make any changes to the settings you're supposed to close content, then reload the core then reload the game otherwise it will likely crash. Most settings don't even change until you restart Retroarch anyway.

Works..... Thanks

if you're playing iso/cso, installing extra wouldn't really do anything. unless the game actually forces you to do so?

 

[D4X]

Essentially a PSP with a much larger screen and detachable controllers! The Switch emulator scene is only getting better and better. Excited to give this a go.

 

[Skaidus]

Now go play freedom unite online with hunterverse

 

[raxadian]

Games that rely on 2D look like HD Remasters when you set the internal resolution to 1920x1088 and run flawless with OC on high (No max necessary). It's truly amazing,
Check out this comparisons.

Hence why some "ports" from PSP to PS4 are just the game in an emulator with fancy effects.

For a remaster it works pretty well. Now I would not like if they call them remakes or something.

"A remastered version of the original PlayStation game was released for PlayStation 4 in 2017 for the game's twentieth anniversary." From https://en.m.wikipedia.org/wiki/PaRappa_the_Rapper

That's the game "port" that was hacked to find it runs on an emulator.

to be fair what is a "remaster" other than a marketing term for a port?

Sometimes is used to sell the same game that a year ago but with all patches on and maybe a few extra levels. But nowadays the term "Golden Edition" or "Game of the Year" is used for that instead.

Sonic Mania is notable because it just added a "Plus." due to Encore mode and two extra characters.
