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

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.

Saturn is harder to emulate than PSP we can hope but it will be really hard.

We will probably have DS before something about saturn

There's already MelonDS and Desmume for DS.

 

[chocoboss]

Yes but in 10 FPS without oc :')

 

[EmulateLife]

You can say the same thing about PSP, you can say the same thing about a lot of N64 games. You acted like we didn't have DS yet but we do.

 

[satel]

Yes. Is the jit version.

i look forward to the superior Jit release,many thanks.

 

[proffk]

When jit version is out its going to be a game changer

 

[Purple_Shyguy]

Whatcha gonna do brother, when the JIT PPSSPP gets a full release, daddyo.

Let me tell you something jack. Mx4w has 30,000 screaming hombrewmaniacs, brother, and come Summerslam he's gonna drop a release that will go WILD ON YOU!!

i'm not quite sure if this is really normal, since i'm hearing people describe the way stuff runs as flawless or perfect, and while it certainly feels like everything is running fullspeed,visually, something seems off.
like, its hard to describe actually, if i compare the way the cursor moves in persona 3 on switch and on a psp, it seems a lot more fluid on the psp.

same with zacks walking animation, it feels like there are frames dropped or maybe stretched or dublicated, but at the same time, it's also not the same as when you activate frameskips. i just can't explain it, but i feel like it'd make me seasick if i played crisis core for an hour or so.

is this just me being really used to 60fps in this modern day? or is there maybe a setting outside of the core specific options that could be causing this?

 

[fst312]

RetroArch does support online multiplayer. Personally though I think I'd like to connect with xLink Kai so emulated + hardware players can play together

Retroarch does have online support but the problem is, hopefully I’m wrong, I think snes is the furthest it could go without seeing lag. Not too sure but does xlink support handheld systems, that would be nice if it could work the way you mentioned.

 

[lordelan]

I'm still hopeful for Dreamcast/Saturn one day.

Same here. Just love the Saturn (don't care about Dreamcast that much though).
But let's be patient for now.

 

[Ann0ying]

Ff7cc is 60 on basic clocks.
Mgs is 30 slightly OC.

vsync off?

It crashes for me as soon as I try to increase internal resolution. Not sure what I did wrong. Other than that LocoRoco, Patapon and Motorstorm Arctic Edge seem to run fine, but I didn't spent more than 1-2 minutes in each one.

SX OS, HBL, FAT32.

You're getting Arctic Edge to work? All I get is the game at the loading screen. After several minutes the game still wont advance beyond that.

Yeah, it works, but you didn't missed much. 20 fps, no sound in race and vertical lines not exactly pleasing experience. But still nice to have it working.

[EmulateLife]

I'm pretty satisfied already with the games that work because I have most of my PSP games installed on my PS3. The only two games I hope one day work is Killzone Liberation and Resistance Retribution. But I know those are two of the most difficult of all PSP games to emulate. That and just text on Metal Gear Acid 2 and Metal Gear Solid Portable Ops.

 

[Xecutar]

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

The wait is so long lol..

 

[Silent_Gunner]

So, I'm watching MVG's Nvidia Shield TV video just for curiousity's sake, and I noticed that, on God of War Ghost of Sparta, he's only getting 50fps. I take it that the Switch, even with the dynarec, is going to have trouble with the games that PPSSPP usually have trouble with on any insufficient setup that can play some PSP games fine except for the more demanding ones? Or do you got something for us power lovers that will subvert our expectations!?

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

IR JIT at max switch clock speed.

Tekken Dark Res = 52 fps
Tekken 6 = 41 FPS

Not bad at all. PPSSPP code bases are really well coded.

Did Tekken 5 Dark Resurrection slow down and/or experience any visual glitches on that sunset stage where you're at some foundry or something? Because on an old 17" craptop of mine, that's how the game ran. (seriously, don't get a 17" laptop if you're mainly going to be using it for school, ESPECIALLY if it's going to page to the HDD!)

 

[masagrator]

@Silent_Gunner Ghost of Sparta works in 30 FPS as default. 50 FPS is only because of 60 FPS hack. So it's playable.
Many games on PSP works in 30 FPS as default. Take it in mind.

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.

Reinstall retroarch.

Delete retroarch-core-options.cfg and voila.
