Games stuttering a little bit

edmaul69

@knorde game mode isnt always in video section. It is often in like extras section or something else. Look in all menus for it.

@edmaul69
I have looked in all the menu's but i can't find it.
I have tested it on my tv on my bedroom.
It is a Tatung V32MCHK.

With the default emulator it is stuttering again but with the nestopia emulator it works like a charm!
No stuttering and it works perfect!

But on the tv in the living room it is stuttering again on that emulator.
It looks like i have to find a good combination from emulator and tv.

With long testing i found more information and a fix (but creates another problem).

Sega games are working perfect now without stuttering (when i choice select default video mode and select the resolution).
But now the NES...

When i choice lr-nestopia as emulator and i set "select default video mode for lr-nestopia" to 1920x1080 60 hz it works perfect!
No stuttering anymore.
When i do the same with the emulator lr-fceumm it don't fix and the stuttering is there.

The solution is that i use the emulator "lr-nestopia".
But... the emulator "lr-nestopia" plays all the game music and sounds faster.
In the Netherlands it must be slower.
When i use the emulator "lr-fceumm" the music and sounds are normal but the screen is stuttering.

Now i have some questions:

What means the clock settings (when i choice select default video mode for lr-nestopia). I see different resolutions with different clock settings. I don't like overclocking. What does the clock settings there means?
How can i get the music and game sounds for the emulator "lr-nestopia" normaal (the same music sound speed as "lr-fceumm"?
If 2 is impossible is there another nes emulator what i can use (and how to install that)?

Quoted from: https://github.com/retropie/retropie-setup/wiki/nintendo-entertainment-system#roms

If you want to use PAL roms, make sure they contain (E) or (Europe) in the filename, or else they may be run at the wrong speed.

@mediamogul
I have tested (E) and (EUROPE) in the filename (it was named already but i try both).
The music play to fast.

On the lr-fceumm emulator it plays the sound normal but the game is stuttering.
On the lr-nestopia emulator it plays the sound to fast but the game is not stuttering.

The quicknes emulator does exact the same as the nestopis emulator.

The questions are now:

What means the clock settings (when i choice select default video mode for lr-nestopia). I see different resolutions with different clock settings. I don't like overclocking. What does the clock settings there means?
How can i get the music and game sounds for the emulator "lr-nestopia" normaal (the same music sound speed as "lr-fceumm"?
If 2 is impossible is there another nes emulator what i can use (and how to install that)?

I believe the selections you're referring to are actually video refresh rates rather than overclock settings.

How can i get the music and game sounds for the emulator "lr-nestopia" normaal (the same music sound speed as "lr-fceumm"?

You said that "it was named already but i try both". If this is to mean that either (E) or (Europe) was already in your file names, try removing them instead to see if that corrects the speed.

If 2 is impossible is there another nes emulator what i can use (and how to install that)?

There is also lr-quicknes. It can be installed using these instructions.

@mediamogul
I has tryed lr-quicknes (see my post above).
It does exact the same as nestopia.

Are there any more emulators or is there another option to fix this?

Maybe test with USA variants of those same ROMs and see if you still get the same issues.

I'd recommend looking for a complete "No-Intro" romset of all the NES ROMs and just extract the games you want from that to your RPi. Stay away from the "Goodsets" romsets.

No-Intro = one good ROM for each region or revision of a game (usually one US, one Europe, and one Japan) and no hacks, bad dumps, homebrew, etc
Goodsets = a collect of as many known dumps as possible into one set including the good, the bad, hacks, multiple dumps and homebrews

You've hit the bottom of the well I'm afraid.

or is there another option to fix this?

Did you try removing (E) and (Europe) from the file names? If that fails, a USA ROM set is your next best bet.

I would honestly format the memory card, re-download the image from the RetroPie site, re-download the ROM from some other site, AND try it on a different TV. I'm afraid that's the only way to limit some of those factors (and to be honest only way to truly troubleshoot is to try another Raspberry pi, another power supply, another SD card, etc)....or that's how I always start my troubleshooting at least by eliminating hardware possibilities for problems, then going into the software again.

As a last resort, going nuclear can be effective. But I can't help but think in this case it's a bit like playing 'Duck Hunt' with a punt gun.

With the sheer number of unexplained and so-called one-off issues I have on an extremely frequently basis (and others seem to have then post about as well), it's generally my first recourse. What takes longer? Re-imaging the SD card and putting in a USB preloaded with your ROMs and wait for them to copy over (and if you edited any configuration files, you should have saved those so they can be copied over in a second), OR, is it better to spend literally tens of hours researching things to try, posting here, sometimes waiting DAYS for people to reply, then spending more time trying those 'fixes' - MANY to no avail (like the OP seems to be at now)?

I choose the Nuclear option 9/10 times ;) - this is exactly why you'll see quite a few topics from me where I tried all these different things...then never post in that topic again - that's when I said "F it", and reformatted that specific problematic SD card (i.e. gave up – as sometimes it's just not worth the hassle).

@Dochartaigh is it possible to download an older version. Ie. The 3.8 you mentioned as working 100%?

I know this was intended to be the undesirable option, but I would always take a researched understanding of how things work over a clean slate approach any day. If you're constantly reformatting a drive to solve every problem you have, you're never learning anything that could help you more easily solve future problems. I guess it's just a difference in philosophy and I can actually see how attractive the nuclear option is from time to time, but in my experience, this approach is more likely to lead to a cycle of problems that are never solved.

@zulueffendi

I run RetroPie 4.1.12 with 38 systems and apart from some very minor exceptions, the current version runs very well.

I have tested it with a usa rom but then the music plays to slow.
It looks like there is no solution for this.

I think i have to accept the "to fast music".
Or someone has a solution...

Don't understand why other people don't have this problem.
I have tested it on 2 different tv's en both are the same problem.

you've not given us any information to recreate. what rom? what file name? maybe a video of the 'fast music' so we know what to look for?

zulueffendi

@mediamogul yes but you are running a pi3 ... We are experiencing new problems on a pib+ where we didnt have problems before. And i overwrote my sd card where my b+ had 0 issues emulating the games i wanted.. the big problem i had was with forgotten passwords. So i thought id start over. Now im experiencing issues abd dont particularly want to buy a newer pi when i know the older one is capable

@zulueffendi

I just read over your particular problem with NES speed, but I couldn't find a reference to what all you've attempted so far.

zulueffendi

@mediamogul overclocked,. Used nestopia instead and used most of the resolution settings. I have dialed in to about 90% of normal speed now..

@zulueffendi

Have you tried the RetroArch configuration improvements listed here? Alongside it's recommendation to set video_threaded = to "true", you might also want to try setting it to false as well.
