find it...thx

@abj Thank so much!!!

@Lolonois Good ideas!

Did you consider to use sshfs [1] for mounting the image/video folder from the main Pi into the PiZero2W? That way you don't need to maintain a cache at the PiZero2W.

I didn't consider sshfs, I started with the idea of a cache from the start to speed up the display. My thought is it will always be faster to read a file locally than over wi-fi, or spi. As a USB-peripheral there may be a low enough lag to skip the cache.

Another idea, albeit more complex, as the current setup assumes the Pi's can reach each other via wireless, right?

It does. However my first idea was to run the zero as a stand alone access point and only connect RetroPie to its network. (My router sits on top of my arcade cabinet so RetroPie is connected via Ethernet and doesn't need wi-fi to scrape or connect to) I didn't implement idea yet for speed to get it working in the first place and I figured that would be an edge use case at best.

You may also run the PiZero2W as USB-peripheral to the main Pi, connected via an straight USB-A to MicroUSB-B cable (and powered from the main Pi). With some configuration the PiZero2W is set into gadget mode

That's actually a great idea! I setup a a ZeroW to be a networked thumb drive to run my SLA 3D printers a long time ago and they're still running great. That would simplify wiring and power supplies.
Only problem in my case is lack of USB ports. I have an arcade deck, trackball, USB SSD, and a 4 port hub mounted to the front to allow plugging in other controllers like NES, SNES PSX ect. (With the USB keyboard and mouse dongle plugged into that). I don't have a free port without adding another hub or taking cables outside the cabinet.

@Souciot said in Audio devices not found GPi case:

@G30FF in the readme of the patch it's written : "Why need to install display GPi Case patch for Retropie and Recalbox?" so I suppose it shouldn't mess with retropie ?

I only have experience with the GPi Case 2, so my mistake. The GPi Case 2 patch includes one for Recalbox 7, one for Recalbox 8, one for Batocera, and one for RetroPie. I downloaded the GPi Case 1 patch, and I see why the recalbox string is there, because it's included in the patched config.txt. Sorry, I won't be much help here.

@IceChes1 said in What will RetroPi run on a Zero W?:

If SNES runs at 10 FPS on a Zero, I wouldn't be surprised if N64 emulation set it on fire.

You can run SNES using the older snes9x cores and performance is acceptable as long as you aren't trying to run superfx games. Even psx performance on the pi zero is not bad using the standalone emulator.

Thanks all for your help. I found a good image for the Pi0 and dont have any problems now :)

@SolemnSpirit Thanks that helped!, the moment i remove the key_mgmt, i was able to connect to the wireless! :D i appreciate you posting this!

@suikodentir Care to share how exactly? It may help others in the future.

@KN4THX said in lr-Stella on Pi Zero W?:

@chubsta It runs pretty good for my tastes. I built a Pi-Cart with the PiZW and it ran Atari up to the Super NES/Genesis era just fine. The rom lists/artwork seem to lag a little with but with a lighter theme that can be just fine.

Thanks very much, I'll get one ordered!

@barbudreadmon yeah, think you are right, it was just a thought i had whilst planning what i needed to buy. will go for a 3bplus as at least i already have very good images so it should be an easy install

It was the bloody power source! I didn't bother hooking it up to a decent power brick because I figured the Pi zero didn't need as much juice as my Pi 3... Idiot... Thanks for your inputs guys.

Try gpsp's non-retroarch version. With this version, you'll probably have less lag on GBA games, since it consumes less resources than the default retroarch version.

I've tested this version on a Raspberry Pi 1 B+, and I remember playing some GBA games without lag. It was on 2015, and back then, if my memory serves, there was no lr-gpsp yet.

I don't know if it'll work on your Pi Zero, but assuming Pi Zero and Pi 1 has approximately the same hardware, there's the chance that it can work.

@madmodder123 no. Rpi update isn't really recommended unless you know what you're doing/have a specific use case as it can cause bugs. If one wants to start with stretch they'll need to flash the latest beta then just update from the setup script/ normal raspbian packages

@Andrewdodo123 Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first (as you agreed when registering on the forum).

Please use a descriptive title - rather than "Help needed". Also do not bump posts - wait patiently for a reply.

Perhaps you have a bad Sdcard or you have written the image incorrectly.

@zerd_sword hi!

I have this very same issue with a recent purchase.

Got a RPi Zero W v1.1 and Retropie hangs after a while. It occurs while emulating SNES and NES (the only ones I tested), copying data via samba, browsing scraped metadata, and even while sitting idle on the ES screen. It seems random but it appears to happen after the system is warmed up, although I removd the official case I got to no avail.

I only have the one so I have no means to verify other board does work indeed, so I was wondering whether you figured out how to identify the faulty hardware. Was there anything different on the new one? Different manufacturer maybe?

Here's a picture of my board printed data: https://drive.google.com/file/d/1iSIXzlZtVigopNxecTbHC9xb4ylrXizs/view?usp=drivesdk

If you have any info, please advise.

Thanks!
