PPSSPP Switch Beta Release

1.jpg

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 ;)

Libretro Docs (important informations for this core):
https://docs.libretro.com/library/ppsspp/
Official Game Compatibility Tracker (your mileage might vary): https://report.ppsspp.org/games

GitHub (WIP Switch): https://github.com/m4xw/ppsspp/
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.

You're still asking him to do something that you will pass on to SX which he hates, why would you think he'd do that? Pretty sure that same thing happens with Atmosphere anyway where you can't change cores without closing content. It's something everyone deals with.

why do people always think wrong !!! i wasn't asking him to fix it,i was asking if he can tell us where the problem is so we can tell TX team to fix it !!
I don't think the problems are exclusive to sx os at all. The core is awesome but it's still beta, some bugs still need to be squashed.
Lol you're not paying atention m4xw hates SX and everyone who uses it.
Hope that's not true. :unsure: I admire him a lot. I'll maybe switch from sx os to atmos when they implement emunand. Can't wait to try out some kips and sysmodules.

i didn't realize it's a personal issue with TX team !!! also i recommend that you read replies before commenting because i did say that i do close content every time !!

i probably will make the move when emunand becomes available but for now sx os is here to stay even if it means i can no longer use retroarch,also there is other options for emulation on the switch but sadly for me no standalone emulators for PSX & PPSSPP

One of the main reasons psp emulation isn't recommended on sxos is because sxos can not overclock gpu & ram. I'm surprised TX hasn't added overclocking yet.

That is false, you can get the same extra ram by holding R on a game with sxos same as atmosphere. In fact it was that way on sxos first as Atmosphere used to use title replacement. You can overclock cpu with Retroarch using sxos too. Although you're right it about it can't overclock gpu.

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

Honestly I'm using sxos and both PPSSPP and N64 are working great. I don't really know why others are having problems and I'm not. I use nro2nsp forwarders and Retroarch nsp could be why or some other reason.

Forget it I'm just putting you on ignore.
You're obviously a noob. You know nothing about the switch, you've made that clear. Holding R when opening a game gives you access to more ram. Why do you need to do that? Applets don't have access to all ram, that's why. Accessing more ram is not overclocking ram noob.

Ventured into a few more obscure titles:

Diabolik Original Sin
(Point n' Click Adventure)
plays perfectly on default settings

Brothers in Arms
(an actually great Gearbox FPS)
Sadly drops frames and crashes on progression - might still try a few settings tweaks

Shadow of Destiny
(Konami non action Adventure :) )
Plays perfectly with only fast ram (speedhack) disabled.

3rd Birthday
(Basicallay Parasite Eve 3)
Plays perfectly on default settings.

Tomb Raider Aniversary
Needs fast ram (speedhack disabled) to not show texture glitches, and stutters, presumably when content is streamed in. Tried other speedhacks, didn't help - essentially more or less unplayable.


Still on my list to test (maybe, we'll see)
Star Ocean 1 and 2
Valkyre Chronicles 2
Crazy Taxi
Ape Escape
50 Cent Bulletproof
Parappa the Rapper
Oddworld 1 and 2
Ghost in the Shell: Stand Alone Complex
Free Running

If you come across some more obscure titles, that for whatever reason you'd want to keep on your micro SD, be sure to share them in here. :)

Another title I've almost tried was Sweet Fuse, but that turned out too obscure - even for my tastes, so I didnt. ;) Thought I mention it though.

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

Also, I'll take a look at finished translation projects
https://www.romhacking.net/?page=translations&platform=44&languageid=12&perpage=40

later. :)

edit: I'll probably take a look at those two:
https://www.romhacking.net/translations/2011/
https://www.romhacking.net/translations/2019/

The other ones, not so much.. ;)

dot hack link translation (cso) runs perfect for me at 2x resolution no overclock. Same with Final Fantasy Type-0 translation (iso).

I was wonder how CSOs would play on the Switch, so I did some research. I read about some games not liking to be compressed, like the GOWs. Haven't CSO'ed those, yet.

Pop Cap has some fidgety games. Peggle does not like CSO and gets glitchy, but is perfect as ISO and I've yet to get Bejeweled 2 functional in any format.

Mega Man Powered up had a 131 KB difference between Level 1 and Level 9 compression, lol.

A number of others only had a megabyte difference between Level 1 and 9.

Here's some other size examples
ISO/CSO

Angry Birds 165 MB/17.2 MB

Ben 10 Alien Force Vigilax 1.53 GB/917 MB

Cubixx 136 MB/24.3 MB

Freekscape 210 MB/52.8 MB

Kurulin Fusion 133.8 MB/21.5MB

Spaceball 170.8 MB/20 MB

Should've re-done Ridge Racer 2 to get the numbers, but it plays.

I've never had real interest in playing a Mega Man game, but that SNES remake looks so superb on the Switch with the core set at 1440x816. Hard as blank, so I use these codes below.

_S ULUS-10068
_G Megaman Maverick Hunter X [US]

_C0 All Weapons are Charged when shot
_L 0x00232D75 0x00000003
_L 0x002271C4 0x00000003

ISO - 728mb

CSO (compressed with ciso-xp) - 461mb

CSO (compressed with maxcso) - 443mb and took approximately 2 hours

What I use is called ISO Compressor and takes minutes.

Angry birds is not 150GB (150000MB is 150GB.) zopfli

I don't know what you're talking about and the Angry Birds 150,000 MB was an, obvious, oversight.

Do you people have no reading comprehension? I said to enable zopfli because the guy asked for the absolute maximum compression possible. That option specifically is what causes maxcso to take so long.

It's not on by default. Without it a 1.2GB game takes approximately two to five minutes with the tool I suggested and uses all the available CPU cores for the job.

cso's (maxcso created, not using zopfli, but --block=16384), play wonderfully - except when they dont. 99% success rate without additional lag or stutter, except for Final Fantasy Type-0, that game crashes after the memory card screen, if you convert it to a cso. (And needs some extra encouragement to run at all, read this thread.. :) )

I'm using .cso as a default now. 20 GB of games make it worth it.

Anyone know why I continually get a "The software was closed because an error occurred" message after I attempt to boot Persona 3?

Im booting via iso and I'm booting Retroarch via the title and through the album.

I do have error messages in my Core Information section regarding the flash0 and asset files, but I have included those as the guide stated so I'm at a loss..

I'm getting the same error on SX OS when I try to load 7th Dragon 2020 II.
