Games stuttering a little bit

@edmaul69 i switched to nestopia and overclocked. It is much better but still slow. Its strange the nes emulation worked 100℅ a couple years ago,.. so imagine my disappointment

I bought a canakit pi b+ kit a few years ago and installed an old version of retropie .. in my limited memory brain i feel like it was version 2. Something. Well it ran awesome. Nes emulation was what i was after.. i wired my own arcade controls to the gpio..

Fast forward two years of really no use and the whole pi awaiting an arcade cabinet build.. i thought id see what was new in the retropie world so i downloaded the new version which is super streamlined now.. but now the shock sets in... I cannot run any nes roms at anywhere near normal speed...

Has anyone else had this issue with newer versions of retropie? Ive tried another sdcard. And lowering framerate to 640/480..

I'm experiencing this myself 100%. Everything from like RetroPie 3.8 to 4.1.5 has Nintendo being 100% proper (60 FPS nearly constantly, no stuttering). Whenever I upgrade any Pi to the newest 4.1.11 version of RetroPie the lowly NES emulation stutters and stammers. WAY more evident on my Pi Zero 1.3's, but have noticed it just a tiny bit on my Pi 3 as well. Switching to lr-fastnes cured it but that isn't supposed to be as accurate or as stable as the default lr-fceumm.

As I always say: this has been tested on multiple Pi's, multiple installs, multiple power supplies, multiple SD cards, etc.

I have a panasonic tx-42as600e.
Can't fine a option to set it to game mode.

@Dochartaigh
It is also with the megadrive emulator.
Is that working perfect with a older retropie version?

Megadrive/Sega Genesis never gave me any issues, even on the Pi Zero 1.3 it's been excellent.

I found this document:

Gaming Performance

"By switching into the Game Mode from the Options submenu in the Picture Menu, the AS600 displayed an input lag around 48 milliseconds, which is below average for a Full HD TV. For the causal gamer it won't really matter but the more dedicated game players will undoubtedly find that too high for their needs."

So you might experiment with this. It sounds like it might add an input lag on that TV :-(

@Dochartaigh

thank you!!! I thought i was the only one.... Sounds like there will be hope for me yet...

Don't hold your breath. Most of my problems I'm told I'm the only one and RetroPie has been downloaded over 450,000 times... (yes BuZz, thats you I'm quoting lol :')

@Dochartaigh hilarious.

Thanks for the reply!
There is no game mode option in the submenu in the picture menu.
I don't know why they say that.
I have found a manual from my tv and can't find anything about game mode.

BuZz

@knorde According to the manual there are some post processing modes available. try changing some of the video processing modes (noise reduction, 1080p Pixel Direct, etc) and see if it helps.

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.

knorde

@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.

knorde

@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"?

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.

knorde

@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?

@knorde

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.
