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

[bbcali89]

Out of curiousity, why can't my newborn whipe his own ass?...

good question. ask him next time.

anyway, im assuming its lack of developers.

It's only been a month or two since HENkaku was fully released to the public.
And RetroArch has only been out for half that time.

It should be fairly obvious why the Vita, a locked down system to begin with, has yet a decent emulator under its belt, no?

Yes!

Some people are never happy. Until now I was able to play NES, SNES, MegaDrive, CPS1, CPS2, NeoGeo, NeoGeo Pocket, Sega CD, PC-engine, GameBoy and Wonderswan without a hitch... Give them time. The party has just begun.

since henkaku has just come out (around only 2 months) , i think that the actual emulator state is great. Hope to see soon a 60fps FBA!

Well, i hope we can use retroarch like it one day.

As you can see, frangarcj got PCSX ReARMed to go ingame now, but there are still some problems which might be outside our control and might have to do with the toolchain. We have to compile with -O0 (no optimization levels) because -O1 or -O2 will produce crashes/other issues. So we need a way to toggle all optimization flags.

awesome news

Mmm strange thing: after i have installed mame2003 (and try it), now fba and fba2012 didt recognize other roms. Only sfiii and tmnt, that i had previously played with fba before installation of mame... so now i need to re-install again all retroarch emus?

Yep done the same on mine. Looks like it effects the retroarch config.
It started when I had played a few games on the Mame verions.
It worked fine then would not load a new game and would reboot the previous loaded game even after selecting a new one.

The "Filter unknown extensions" was then not shown and asked for "open game in folder" or "open file in core" options and games would not load.

Just restart FBA or any other core and change the "Filter unknown extensions" to on and save config.

That should sort it out.

I just tried in this way. And later yesterday i've tried the harder method: i uninstall all my retroarch emus, deleted the retroarch folder from data folder and re-install everything again, but now (even without MaMe), my FBA emu didnt recognize any rom o.o
I start to think that maybe is fault of newer version (nightly 22 i used; before i had 5th and 14th september build, and maybe with these will work...)

Have you tried the MVS version?

I use that for neogeo games now and have activated the UNI-Bios in "quick menu" "options"
Gives you cheats and other options too.

try https://github.com/recalbox/recalbox-os/wiki/Use-Neogeo-Unibios-(EN)

It kick started my setup when I had problems with loading roms for neogeo.

What mean MVS?

Anyway SFIII 3rd Strike its not neogeo, right? Is CPS-3, and FBA stop detecting even this game...

The Neogeo version of FBA retro arch.

You will have to load a working rom and escape to menu to get the quick menu

Ive not tried the CPS-3 only CPS-2

in unibios you can select AES or MVS so console or Arcade cab version.

You can also add blood to say Metal Slug , extra lives etc

It's all explained in https://github.com/recalbox/recalbox-os/wiki/Use-Neogeo-Unibios-(EN)

you dont have to use that one any in your neogeo.zip if present.

I've used CPS-3 until now... so technically works. But now...
And really neogeo bios allow cheats? But not for CPS-3 game i suppose
Anyway i cant load any roms now, so cant load neogeo roms to set the bios... the Load Content only detect the snes9x folder (that are empty for FBA, even with show unknown file extension). I have FBA and Snes folder in playlist, and set the Load Content from here.

EDIT: Please, someone help me!! Retroarch dont work anymore to me o.O
I've tried to install, uninstall and reinstall many times builds from 14th september, 21th and 22th, deleting many times retroarch folder from data, but now retroarch didnt recognize any folder of roms!!! I cant load game, why??

Just use the Snes core to SET the load content "Filter unknown extensions" to on and save retroarch current config.

 

[laharl22]

Pcsx come soon i hope

 

[Lord M]

Just use the Snes core to SET the load content "Filter unknown extensions" to on and save retroarch current config.

I've tried, both with on and off, but nothing
At least now i can see snes roms, but i think i can start to say goodbye to FBA...
My first build that was working was 5th Sep; why I deleted it? Someone here still have it? Maybe with 5th build FBA start working again...
Anyway RA say that Core directory is in app0 or ux0/app0, but here i see nothing, its normal?

 

[VincentBeasley]

So whats better, Picodrive or Genesis plus GX? And can either of them play Sega CD games correctly now?

Been playing Sega CD with Genesis plus GX for quite a while now. Haven't tried Picodrive yet.

Well I know that Genesis plus GX can play them but it used to mess up if you used a save state or put the vita in sleep mode

I've not played with the folders like that.

I would uninstall all retro arch cores using the icons on the ps vita and then install the new version.

try that it worked ok for me.

 

[LibretroRetroArc]

The commits were merged, hopefully the next RetroArch nightly has a working PCSX ReARmed core right now.

Note - even though the dynarec already works, things can still be slow because we had to disable all optimization levels in order to get it to run. The next step will probably be for frangarcj to talk to the Vita toolchain developers to find ways of enabling all optimizations so we can get better performance. Fundamental errors happen when compiling with -O2 and ultimately we really need to be able to compile both RetroArch and the core with most general optimizations enabled.
