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

[xoleras20099]

It's annoying because we'd like to set different video modes for different cores. Depending on their native resolution, you might want to enable or disable integer scaling, change the aspect ratio etc.

Go to Settings > Video and change the aspect ratio from 4:3 or 16:9 or whatever you have it set to, to "Per Core" or something (it's the last option) , it picks the correct aspect ratio depending on the system (MAME is the only exception as different arcade machines have different screen sizes)

This works in theory, but in reality this is not necessarily optimal.

For example, we might want to use integer scaling with GameBoy games to allow us to use a border overlay, whereas with MegaDrive or Snes games this is not optimal because we want the image full screen 4:3. Some formats are better set to 1:1 PAR, whereas others are better forced to 4:3 due to using non-square pixels (CPS2).

Ideally, we really want to be able to manually optimise the video settings for each individual format.

The Neo Geo is special in that the neogeo.zip file has to be in your rom directory.

Don't use 'Load Core', use 'Load Content'.

Hmm, the stable seems to revert the naming back to CATSFC, Snes9x Next etc., and doesn't include CATSFC Plus or pocketSnes at all, nor the PCE core.

EDIT - In fact, it just had .velf

Thanks!

Yes! I see that this updates regularly after a new nightly is released.!

...I-I try to keep this updated as Nightlies leave the proverbial oven. >~<

And thaaaat's because the stable build was made July 16th, while the .vpk nightlies didn't start coming out until August.

Is there a way to set the back touchpad as extra buttons if you are using a L2/R2 grip?

 

[megadrixfire]

I hope they fix dosbox soon anyone tried it on the latest builds..?

 

[SeongGino]

I would make changelogs, but... nothing's changing.
The filesizes are the same for the last August 8th and current August 9th nightly.
Dynarec is clearly the focus now.

Does it need a bios for cps1 and cps2?when i open a ROM on ZIP format it close the core it the same for Neo-Geo it close the emulator i have the neogeo.zip BIOS on system folder

cps1 and neogeo doesn't work at all in my case using retroarch so i use cps1psp and mvspsp using a vhbl bubble for now. cps2 works for the most part with the main game i came across that did not load so far was super street fighter 2 turbo/x grand master challenge.

neogeo bios has to be in the same folder as the games to work.

Thanks but why cps1 doesnt work?

Which Nightly are you using?

 

[laharl22]

Which Nightly are you using?

The latest

i use fba neogeo 2012 to play kof2003. game was run but the picture is erorr. i use unibios 3.2.

any idea to make it playable? thanks

 

[SeongGino]

The latest

Try the August 7th nightly maybe? But I doubt that's the issue since those haven't changed at ALL recently.

Make sure your FBA ROMset is ACTUALLY from Final Burn Alpha: MAME does not cut it at all.

did anyone test Playstation core yet?

It's not even available at the moment, since the devs are busy with Dynarec implementation.
I doubt it would work fine at the moment, anyways...

Oh, I'm sorry, I only read the OP and thought it was available again Anyway, I think the vita has the potential to run it pretty great.

Without any help from the GPU, and at this early a stage...
Eh, I doubt it.

Thing is, the PS Vita's CPU has been confirmed to be around either slightly slower or faster than the current New Nintendo 3DS. So really, the most speed difference we MAY find might be from the GPU.
Or, at least theorized so far... Yeah, taking off the tin-foil hat now.

I've said this before, the best PS1 emulation will probably be if a 3.60 TN-X exploit comes out...

If the New 3DS performance is anything to go by, it should run many games decently even using software rendering.

An exploit for the official emulator remains optimal of course, but it would be nice to have an open source alternative.

Does theFl0w's PS1 bubble trick still work on 3.60? If so, we only actually need an ePSP kernel exploit, not a PS1 exploit as well.
