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.

Is your Cpu core set to JIT??

yes it is, i have tried changing lots of other settings,even formatted the sd card fat32 still PPSSPP won't run on my console,it was running ok on 1.7.6

When it was working, did you experience audio/input lag? That made the game frustrating to play

 

[gamemasteru03]

I know this is a stupid question but where do I put cheats and textures?

 

[gamemasteru03]

Never mind. I got it to work!

on few games like Atari Classics Revolved,gow & the gta games.

 

[kevinbrew]

Has anyone got SSX ON TOUR working without graphic glitches?

 

[HeroPrinny]

Star Ocean First Departure just blackscreens when you launch it. Anyone got it to work?

Yes i got it working without doing anything special

 

[m4xw]

Btw if anyone missed it: Latest nightly has a new IO timing core option, setting this - depending on the game - will fix titles - or break them.

We just had the game announced for a Switch release today, if you wanna wait on that might have some new content

Settings for Final Fantasy Tactics War of the Lions?

I've noticed in retroarch 1.7.7 in WOTL bilinear filtering remains on even if you turn it off and the music goes weird at points. Any fixes?

 

[Chrona]

WotL has lag built into the game that makes both the video and audio slow down. So I'd check to make sure if you slowdown patched the game first.

 

[ricflairandy]

Cant get this to work atall, whenever i try the switch gives an error forcing to shutdown.

 

[spotanjo3]

Worked great for me. Mega Man X Maverick Hunter's FMV (Europe) running smoothly and Mega Man Powered Up (Europe) running great!

Untouched.

As I recall it also had crappy scaling/stretching by default on an actual PSP. There's a patch for that too.

Ah yeah thanks I see them. I was able to patch the ISO with the lag fix and the stretch fix

 

[Rahkeesh]

In case you do something stupid like me...

If you played with texture scaling level and want it OFF, because you found it introduces massive stutter on Switch, you need to set it to 1, which is the default. 0 appears to make the texture scaling adjust dynamically with your internal resolution, i.e. 2x scaling at 2x resolution, which likely isn't what you want.

Odd I did this and then applied the speed up patch yet I still get some laggy music. Mostly at the begining and Trisection is playing. I OC the retroarch to max performance
