Update on this, I have no idea what is going on, but it seems if from vitashell you copy the file and paste it somewhere else it will then show in the list. I just copied all my roms outside of their directory, deleted the directory, recreated the directory and pasted them back and now I can load them...same directory name and same file names! :/
I not understand well... can you tell me more cleaner? I copy game on a psp savedata, then trasnfer on vita using qcma, then using vitashell and i move games to right directories. Anywai i've tried either to copy and move games, but no differences. And for FBA games how a directory can have same name of files inside? FBA games at least have 2 files with different names...

Alright. Found out how to enable analog. It's under the quick menu.
Same with enhanced resolution mode. Though the framerate drops about half when using the enhanced resolution mode. Really hope to see the enhanced resolution mode become more stable in the near future. That'd really give it the upper-hand over sonys emulator (aside from the fact that it already seems more compatible as far as titles go.)

I recommend using the bios, yes. The OP mentions where those go in.
As for the roms. I'm having no issues? I keep my roms in ux0:/roms/psx
Bin and cue files. No zips, no ecms. Works fine by me, but if you're still not seeing them I'm not too sure what to say.

I have actually had a similar issue to this, where I've copied a file across and Retroarch hasn't actually seen it. I then deleted it then copied it across again and it's been detected fine. I've no idea is Retroarch is at fault however, and I haven't been able to replicate the issue since.

I not understand well... can you tell me more cleaner? I copy game on a psp savedata, then trasnfer on vita using qcma, then using vitashell and i move games to right directories. Anywai i've tried either to copy and move games, but no differences. And for FBA games how a directory can have same name of files inside? FBA games at least have 2 files with different names...

From what I've tried it appears as the "move" command in vitashell is not working properly, I've tried moving the roms to another folder and they didn't show up, I then tried to copy and paste them and they appeared.
Try this, create a new foder inside data/, then find any of your roms that don't show up and COPY, then PASTE it into the new folder. Open up the related core (or any core and disable the filtering) and browse to your new folder, the roms should now show up. Or at least it does for me!

Tested: ape escape, bushido blade, crash 1 and 2, die hard trilogy, parappa the rapper, spyro, and tomba! All very playable. Thank you guys so much for you constant progress. Much appreciated. If anyone has any questions I'd be happy to help.

I'm gonna throw a couple Street Fighters at this later in the day, I think. I just wish I had the storage space for all this fun stuff... I might have to jettison a few PSP games to make them fit on my card.

If someone can test Mortal Kombat Trilogy and Mortal Kombat 4 I would be very grateful! What I care the most is framerate.

do you gus know if there a shortcut to start the games on each core?

I can see a history tab but is always empty.
Going through all the folders each time gets really repetitive and time consuming.

So i need to COPY and put the roms in data/ and not data/retroarch/playlist? (anyway from here Snes and Gba games works...). And i need to COPY only the rom, not the folder? (usually i put the rom in a folder with the name of the game). Or i need to put the roms in another folder created, this is what you tell me?

BTW, the HLE BIOS is very inaccurate.

If a game doesn't work with no BIOS, definitely try it again with a real BIOS, in most cases it should work then.

Sorry to bother you, great fan of your work so far :)

Just a question, is it possible in the future for shaders to be used on the PSVITA retroarch cores?

I love my retrogames to have "scanline" effect on them, and i was using the scanlines overlay but in the last builds they do not work anymore and make the emu crash.

Thanks a lot for your work and for the great advances with psx emulation!

It is possible to inject dynarec to vba next and yabause?
That's not how it works. Dynarec works by taking machine code from one platform (in this case, the PS1's MIPS processor) and reinterpreting it into code that the target processor (in this case, the Vita's ARM processor) can read natively. So, PCSX uses a MIPS-to-ARM dynarec. You can't just copy-and-paste this into another format. For example, the Saturn uses SH-2 processors - not MIPS.

The other two cores known to support dynarec are gpSP and Picodrive (32X and SVP emulation only).

it could be that they dont work yet. everyone (including me) has reported crash bandicoot 1 as working. try that and see if it works for you.

For some reason it seems the problem is related to transferring the .bin file over USB using the MP4 workaround. Transferred both Castlevania Chronicles over FTP and it worked. Same for the others.

BTW, there is a way to make high-res interlaced games like Tekken 3 run a bit better -

turn off 'interlacing'. Go to Quick Menu -> Options, there should be an option where you can disable/enable interlacing. Experiment with this.

It should affect games like Tobal 2, Tekken 3, Dead or Alive, and other games using interlaced video modes.
