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

Genesis Plus GX performance also might be dependent on who has or hasn't overclocked their Vita.

Genesis Plus GX is working flawless for Genesis, Master System and SG-1000. Picodrive is good for 32X. Never tested Sega-cd. You obviously doing something wrong... (tested with last nightly to be sure)

the problem was having rewind activated, if it is deactivated it is perfect


About GBA, Legacy of Goku games have copyright protection, neither with vba-next nor with gpsp you skip it.

It definitely performs fine on stock clocks, albeit admittedly pushing the limits. The aforementioned SCD edge cases describe in more detail.

Rewind is essentially a no-go on Vita due to the added overhead. We just don't have that much CPU time per core to make it happen.

Zzz... did not read your bible nagging. Good luck, kiddo. Stop getting yourself into conversations you were not addressed. Good luck in you high horse, dummy.

Then I'll happily not continue your conversation that you decided to bring up in the first place if you aren't even respectful enough to listen to what I have to say in the first place. But, sure, continue believing whatever you want.

By quoting me, you are continuing the discussion, loser. I will just block you.

EDIT: To FmT specifically, I don't want to come off as disrespectful or anything, and sincere apologies if the last reply that off-handedly mentioned you is indeed baseless; I'm just out of the loop and haven't seen this kind of behavior for the couple of years I've managed this thread.
If these were indeed improvements that could help the Libretro team, did you or would you consider bringing this up with them directly? They could be easily reached on the Vita Nuova or (more obviously the) Libretro Discord. And I wouldn't be too surprised if someone involved with the Vita port just so happened to be watching the thread.

What a little guy...

 

[SeongGino]

Classy.

 

[vree]

Can someone tell me how I can see what version fo retrarch I'm running?

Also is it normal gba games have so much slowdowns like for example megaman zero really stutters...

 

[SeongGino]

If you're using Stable, lower-left corner text tells you the version number.
If you're using Nightlies/want detailed info, Information -> System Information, and check the Build Date.

Also is it normal gba games have so much slowdowns like for example megaman zero really stutters...

If you're using VBA Next, unfortunately it can be pretty slow. gpSP garners better performance, but beware of bugs.

 

[SeongGino]

Updated the OP a bit, but nothing major.

Thanks to a certain someone who I won't be naming, and with the slightly more helpful tip from a friend offsite, I've gone back to some of the older builds dated as far as January (this year) and compared with the newest nightlies. As expected, I have not noticed any regression in performance.

You forgot to mention "MAME 2003 plus" which is a better MAME than 200 and 2003. Have the latest games like Final Fight 30th anniversary, lots of bug fixes (analog stick preferred) and better performance on legacy games than FBA / MAME 2000 AND 2003. FBA is still king for CPS / NeoGeo / some shooters. Romset is a little tricky though.

You think I didn't notice?
MAME '03+ has been in the OP for years now. And its performance is still comparable to the original 2003 core; and if it isn't, then I'm not seeing which games actually benefited from the backported drivers. But I still don't expect leaps and bounds since it's ultimately based on an already-underperforming core with more accurate - and thus, typically more costly - drivers.
I could always check with the set I have just to make sure, but that was the result I had last time I tried it a while back and Libretro hasn't really mentioned any games that gain mostly performance benefits over the original.

EDIT:
And my cursory testing more or less confirmed my suspicions. Take a look at Konami's X-Men;

Here is 2003 non-plus; pictured, the usage graph is shifting between the high 60%'s and low-mid 70%'s.

Here is 2003+; pictured, the usage graph is almost exactly ten percent higher than non-plus, which ranges between mid-high 70%'s and low-mid 80%'s. All of this, for a perceived equivalent graphical and auditory experience (though I'm aware 2003+ doesn't benefit Konami systems as much as others, I'm just making it noted).

Not pictured: I also tried Sega's Space Harrier; both cores are exactly the same both performance and graphics-wise, which is mid-60%'s in-game, and 80%-90% on title screen.

Try Arkanoid then

Doesn't the OC make the already-pathetic battery life worse?

 

[SeongGino]

Not necessarily any worse than running homebrew, which overclocks the GPU anyways.
And it isn't even like the Vita's battery is particularly bad.

I don't know, I feel the CPU is kinda weak

You do need OC for RA, its already set to 444/222 for default, max it out to 500mhz not really see any improvement just drain the battery more faster

Reducing CPU overhead and chances of slowdown doesn't count as an improvement?

Has anyone imported content for PC Engine CD games?
I've tried and it goes through the motion but nothing comes up in the playlist section

This has been a problem for years and none of the Retroarch devs seem interested in fixing it. I think there are some third party tools you can use to build playlists but I personally just use the browse files option to load pc engine cd games.

Or just simple manual scanning would do it. For automatic matching to work, or for grabbing thumbs, you need games whose exact file names are matched to either matching No-Intro or Redump sets.

Thanks I never really knew how manual scanning worked before.
