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.

Switch fw. < 4.0?

nope im on 3.0.0

Your fw. version is not supported for JIT =/
You will need to upgrade to min. 4.0 to use it.

GTA LC looks great but freeze every 3 to 4 seconds

I tried other options, but without JIT patches I literally had to wait 2 full minutes to boot up MGS PW.
It was horrible, but surely could be optimized, but only very little.
So i guess you are stuck with IR JIT/Interpreter for now

I agree with you

def jam fight for ny not booting, gets stuck at back screen both on jit and ir jit (tried also disabling speedhacks)

ace combat x seems to be similar. blackscreen, needs hard reset. also with all speedhacks off (unsafe functions is suppose to be off too, right?) and both jit settings.

tekken 6 also doesn't want to run (it sends me back to menu with no core selected). and I'm also pretty sure i didn't do anything to that iso..

possibly potentially could be a result of optimizing (using the optimizing button) games with umdgen, unless others are having similar issues with these games?

When I run the game.. How do I bring up Quick menu in Retroarch while game is pause ?

i think the default is pressing plus and minus button together

Here is a little compatibility sheet for JIT PPSSPP/libretro on Switch.
It's already a bit outdated, but should give you a rough Idea!

L1+R1+Start+Select.

I'm trying to get Wipeout Pure (EUR UCES00001) with JIT and 60 fps cheat.
Basically:
IR JIT - doesn't matter (speedhacks, 3x, xbrz), works evertything but can't reach 60 fps. Without cheat 30 fps fine.
JIT - Doesn't matter what settings (1x, everyspeedhack off, psp cpu speed not locked, etc.), 60 fps cheat enabled - crash. 30 fps, not sure, but with everything off it doesn't crashes.

SX OS, HBM NSP Launcher, FAT32 32kb cluster.

Tested same cso on desktop PPSSPP no problems with 60 fps cheat.

tekken 6 runs great for me, jit, all speedhacks, mid oc, 960x544, almost perfectly playable

So what's the difference between JIT and IRJIT?

Curious too.

Persona 3 Portable is working as great as ever with overclock at 1785mhz, if you use the base clock of 1020mhz it will lag (25 ~ 27 fps) on 3D cutscenes, tartarus and obviously on battles.

Do 460 MHz GPU and it will be fine on lowest underclock in HD

I'll try it.
Also, Mana Khemia is laggy as hell even at 1785mhz.

ok, no idea why, but without changing anything, the games that didn't work a moment ago now work.... well, at least the ones i hadn't deleted already... guess i'll look for ace combat x again

still kinda confused by the framerate thing i had a few pages back, that seems to be 'fixed' by changing vertical sync swap interval.
it's especially weird in daxter.
the gameplay is much better with swap interval set to 2. but cutscenes only run normal speed with swap interval 1.
some games like megaman powered up and patapon are half speed with interval 2 and need it on 1.


ok, finally got tekken to work, i guess locked cpu speed shouldn't have been set.


can someone try if secret agent clank controls wonky for them too? it's like he runs if i move the stick down or to the left and the right, but he kinda just walks slowly when it's diagonal up and up. and i don't know if it's the game, the settings or these replacement sticks i installed a week ago. i already played around with the analog stick sensitivity setting and it changes the behavior slightly, however i still can't make him run in every direction.

Cant get Final Fantasy Type-0 to run. @seanp2500 did get it to work though. Any pointers would be appreciated.
(Settings, md5 of the rom, which build did you use?)

edit: Got it working, see below.
