Have a look at this article about hdparm! There are many settings you can tweak!

You could also set the sleep/standby timer to a longer time!

@IanDaemon i found that when I'm in game and I bring up the retroarch menu, I can't move anything in the UI. The cursor will not move with keyboard or controller. I'm stuck there until I hard reset the pi because I have no input. I thought about a reinstall but I spent a lot of time scraping and setting up and I'd hate to have to do it all again.

@chubsta It's definitely the images causing an issue, especially if you have a lot of games. All of my Pi Zeros have this issue and I no longer use the videos. If you try another theme or change the UI theme settings to BASIC (I believe) you should see it become very responsive. The Zero is a minimalist board when it comes to resources but it functions extremely well for all of the systems I run on it.

@sebretro said in Periodic stuttering/freezing with RetroPi4.4 on a Raspberry 3B+ in every game (1-2seconds):

Does anyone have know about this problem? Thank you for your help.

Looks like an insufficient power problem - the RPI underclocks itself not having enough power. Take the PI out of the case and do some testing to see if you get the same problems. The NesPI cases are notorious for this kind of problems.

The supported tweaks also yield the best results by far. Setting a television to game mode alone feels like the difference between night and day. Setting even all of the possible unsupported tweaks feels more like the difference between night and a bit later that night.

Whoever could solve the problem with sound on SNES emulator PI3B, PI3B+
The solutions described "https://retropie.org.uk/docs/Sound-Issues/" do not work.
Very disappointed in Raspberry.
Sound sometimes slows down and collapses.

a few days later .... after reading a lot of unnecessary information
The problem was in throttling.

avoid_warnings=2 means don't show the warning squares and don't disable turbo mode on under-voltage condition. We still throttle on over-temperature.

From what I hear, the Pi Zero W has trouble running NES games without certain optimizations. I hate to say, but I doubt you're going to get N64 running well at all.

If anybody comes accross this: Happened to me with version 4.6 (on raspbian buster), exactly same problem, like 3fps on all PS1 games. Tried different emulator (removed lr-pcsx-rearmed from main packages and tried pcsx-rearmed form optional). That ran well, but didn't see controller. So I decided to tweak with original lr-pcsx-rearmed, reinstalled it back and voilaaa, games at full speed. Don't know the reason, but for somebody just wishing running emulator it's worth trying I suppose.

@tonytoon I forgot to mention that the displays I have found are typically VGA, but many of them also have DVI ports. I found a cheap HDMI-to-DVI adapter which is the way to go. DVI cables are bulky, so this little adapter basically upgrades the display to HDMI.

Also, I un-shell them and discard the plastic bezel. This sometimes requires me to relocate adjustment buttons which has not been a problem. You end up with a screw-mountable steel bracket reinforced screen with the driver board/power intact, just not all of the branded plastic.

@mitu said in All ROMs running in slow-mo:

Sounds like a slow video driver problem. Are you using the default driver (amdgpu) or the AMD (fglrx) driver ?

I've tried to install the AMD driver but it gives me the following error:

One or more tools required for installation cannot be found on the system. Install the required tools before installing the fglrx driver. Optionially, run the installer with --force option to install without the tools. Forcing install will disable AMD hardware acceleration and may make your system unstable. Not recommended. See /usr/shar/ati/fglrx-install.log for more details.

Here's the log:

Check if system has the tools required for installation. fglrx installation requires that the system have kernel headers. /lib/modules/4.13.0-32-generic/build/include/linux/version.h cannot be found on this system. One or more tools required for installation cannot be found on the system. Install the required tools before installing the fglrx driver. Optionally, run the installer with --force option to install without the tools. Forcing install will disable AMD hardware acceleration and may make your system unstable. Not recommended.

Just to update, I opted to instead go with Sanwa sticks as they are the perfect size with the same screw holes and apparently the top of the line based on the recommendation of those in the know.

Wireless is appealing for the simple reason that's it has no wires. If I was playing on an old 28" crt that would be one thing but on a 46" led TV I want to sit back on the couch.

While there is less lag with wired, I play with PS3 controllers and haven't had any noticeable lag issues.

@chigundo As far as wired controllers go, the ibuffalo are perfect for any games not needing analog sticks or triggers (no ps1, no 64). I also recently built a picart for my girlfriend and bought her the pihut snes controllers for under $10 each because she never grew up playing games much and I wasn't sure if it would be good to invest too much. These work really well for the price though the ibuffalo and original controllers are far superior but she doesn't notice a difference not having a history or much game playing. The only real downside is a short cable. She also now loves playing frogget and the classics every night before bed to wind down so I am going to upgrade her to wireless so she can lay in bed instead of having to sit on the edge.

@mitu thanks, im try it later)

This arcticle helped me find the right cable. The lag on a crt in minimal. Way better than the plasma.

Well I've tested Sega CD and 32X on my Pi Zero. I used the overclock I mentioned above but with overvolt 2 instead of 6. Sega CD works flawlessly on FMV games and games that use scaling/rotation. Sega 32X is so close to full speed it hurts, but its not quite there. I'm sure if I could squeeze another 100 MHz out of the CPU safely it would work at full speed. It's funny because I remember 32X working good on my Pi1, just not PSX or above. That was a few RetroPie versions back however. This will eventually be a handheld system so active cooling is not really an option. As a result I will likely have to leave 32X out unfortunately, unless performance improves when I lower the screen resolution for the LCD. Out of curiosity, has anyone ever pushed a Pi1 or Pi Zero to 1100 MHz? If so was it stable? How about temperature under load?

Hi guys. I’m new to the forum and stumbled across this post. I know it’s old but I’ve got this exact same problem.

I have the nes30 pro. The lag is unplayable. Sometimes it works fine then sometimes it just does it’s own thing and wanders off. I’m using an 8bitdo Bluetooth dongle since the built in Bluetooth on the pi4 was impossible to get working with this... and also I have a nes30 controller too which was totally impossible to sync up with Bluetooth.

The nes30 controller however works fantastic with the 8bitdo dongle... but the nes30pro just does not work good at all.

Both controllers have had the firmware updated also.

I’m stumped how the nes30 works great yet the nes30pro is really bad. I’ve disabled the onboard Bluetooth on the pi4 in case it was interference of some sort?

Anyone had this problem and got around it? These controllers aren’t cheap either which is more annoying as I’d like I to work.

Thanks.
