Hacking Emulation RetroArch/Libretro Thread: PS Vita Edition! Nightlies Included

[rez78]

Are there any builds for Vita that support cheats for NES, SNES, Game Boy, and Genesis?

Hello. I have a problem. I just added a couple snes games to the roms folder for snes9x2005. But the games I just added are not showing up on snes9x2005. They show up just fine on vita shell. But not in the emulator. I'm not sure what the problem is. Here's some info:

My vita is on 3.60 with latest version of henkaku
Snes9x2005 is version 1.36
The games were transferred with a usb cable using qcma

I'm playing SF3s on FBAlpha. Skipeframe set to 1 and it plays beautiful! So glad this is happening! gonna keep updating RetroArch till no skipeframe is needed.

Did you move them with Vitashell? That must be the case. You need to copy and paste them when moving from one folder to another.
Don't remember the reason (something like "moving" doesn't gives the right properties to the file, while "copy and paste" does).
Hope it works.

I did this. But it still didn't work. Games won't show up. Guess I'll be buying a gpd xd plus.

It may be the format also.

Try other roms.
Or try other method to pass your roms to the Vita: direcly from Vitashell through USB (press Select, you need to have USB to mount instead of FTP on Vitashell menu -press Start to that menu-) .

Make sure they are not still in the Zip File, and make sure they are .sfc File type. Should show up and run good. I remember reading that SNES2010 was better for quite a few Games. Something about lag or stuttering in the 2005 Core

30/09 nightly is huge improvement on fbalpha core, on par or maybe better than pfba (outrun is working flawless). Too bad retroarch is not working on PSTV after 1.7.3 (launch a rom make you back to livearena) but it's working fine on normal vita.

Edit : retroarch 1.7.5 is out but same problem with Playstation TV sadly. There is a workaround though. You need to launch a game compatible with the current core, but from load content, choose directory and get the "current core". After you can use retroarch normally.

How do you compile an individual (official) core? Set the $(platform) variable to "vita" when running make, and it successfully(?) outputs an .a file, but I need a .self file, is that right?

Unrelated(?), is there a quick way to fix the garbage horizontal lines that appear in Super Metroid under snes9x 2005 near the top of the screen? s9x2010 fixes it but is too slow.

OK, I've told frangarcj about this. Hopefully he can help with this.

I tried the C64 core again, and I found that turning threaded video on gives a large speed increase (5-10 fps). I think this is the reason I got Master of The Lamps to run in full speed 50 fps without frameskip before. Without threaded video, the fps dipped to 46 during the 3D levels.

Has anyone tried threaded video in other cores? You might get a huge speed increase.

Well I tested the last stable version (1.75) and FBAlpha is unplayable again, so gonna put the self from 30/09. Thanks, this nightly core really seems faster, but I still need to put skipeframe:1 on SF3s

 

[rsn8887]

Ignore my previous post, threaded video does NOT seem to improve fps on Vita, only on Switch.

Yeah, too late to talk about it, but I tried on SF3s and was worse. So nope, enjoying it with skipeframe: 1

 

[rsn8887]

But on Switch, threaded video works wonders and SF3 runs full speed. It is good to own a Switch.

 

[lucks]

Could it be that vita threading code is not optimized/correct?

Anyway what about extended memory mode? (It is not enabled)

Lucky for switch owners they don't even have to worry about trying to emulate street fighter 3 since the street fighter 30th anniversary collection came out on the system. It's the vita that needs to emulate it.

Hopefully the Vita can get looked into more, to see what can be run on it. Been asking around, and it seems like a good amount feel the Vita can handle more, if properly made.

 

[Zukov]

Please frangarj, we all want SF3s running flawless and is kind of close!

VERY close to perfect. I asked on EmuParadise's Facebook Page, and it seems like the Vita got more Votes, as to my Question on which Device would be better for use of Emulation. The Device I compared it to was the GPD XD .

Spoiler: Specs of the Vita and the GPD XD

GPD XD Specs:
Rockchip RK3288 / ARM Cortex-A17 / 2GB DDR3-SDRAM / ARM Mali-T764 / 1280x720p

Vita Specs:
Quad-core ARM Cortex-A9 MPCore / 512 MB RAM, 128 MB VRAM / Quad-core PowerVR SGX543MP4+ / 960x544 qHD

Now looking at those Specs, the Vita Wins in a few areas. Both have ARM. The XD can run N64, and under RetroArch, can run MAME2010, MAME2014, and MAME2016, but it warms up a bit with 2014/2016. Also, the XD runs VirtualBoy PERFECTLY. Can even run Brutal Doom (with the Doom Touch App). So if the Vita can beat the XD........think we have only scratched the surface of what the Vita can run. So hopefully we will eventually see this Device become a badass Emulation System with RetroArch, and any other Emulator/App.
