@headrush69 Thank you sssssssssssssooooooooooooooooooo much headrush!
I have spent the last 2 days digging for this!!
My volume knob, It WORKS!

I literally created an account here just to thank you!

No, no, I get it. I wanted the optional emulator anyway but the problem is clearly with the roms/images and not with the emulator. I appreciate the kick in the right direction.

I was pretty sure I installed the supergrafx emulator but it wasn't showing up when I was selecting it in the list. After installing it manually from the source it came up as selectable and showed the problem was not emulator related.

@mitu It's possible but I think it was my installation of lr-pcsx-rearmed because I had another psx game crash on me which now works fine since updating it.

I also have the same condition with the Pi 3B+ and NESPi+ case running most recent RetroPie 4.4 release. It seems to happen with all wireless dongles connected in to the NESPi case ports (wireless Keyboard, and Xbox 360 adapter for sure). I found a couple different threads in the forum about it and I believe they found the reason, https://github.com/raspberrypi/linux/issues/2408, and I believe they were working on a fix, but I have not seen the true fix anywhere.
(If anyone has it and a step-by-step, I'd be grateful)

**I did find a temporary workaround though, without having to revert to previous Pi versions-
Use another USB hub (like a laptop 4-port) to connect to the NESPi case, and then connect your devices in to that. It appears to cancel out whatever mismatch there is between the pi and NESPi USB hub.

It's a bit unsightful but it prevents a lot of re-imaging and reversion to a previous release. Hopefully a solution will be embedded in to the next release as the NESPi case is great!

*I have been successful using either an Insignia 4 port USB2.0 Hub (N5-PCH5420) and also with a Sabrent 4 port USB3.0 Hub (HB-MNBW). Not sure if a powered USB hub will do the same but worth a try before frustrating yourself to no avail looking for a solution.

My devices connected were a Microsoft Xbox 360 Wireless adapter, and Logitech K400r wireless USB keyboard.

Good luck out there..

What device, just a name will do. Much like the HyperSpin set-ups that cause no end of aggrevations and its really just shovelware with no thought. It annoys the hell out of the HyperSpin guys as their software is also basically FREE

Is it wireless or wired connected. If its an add-on thats not working on KODI, add-ons come and go. Especially 'unofficial' add-ons that get taken down through the authors get threatened with legal action for streaming content they shouldn't be

Personally though, if your having problems and the 'customer support' is useless then you would be better off starting again and install from scratch as suggested as aftermarket support by these 'sellers' is patchy if any

Get another SD card,or even better an 4GB SD card and an external USB powered hard drive, NOT one with an external power supply (well you can but its just more space). The portable USB gard drives are very very small, about the size of a small mobile phone and will easily power off the PI you bought

You can then keep your original SD card and install OSMC (basically a complete KODI 17 install that works straight after installation) then install RetroSMC which will then add a full genuine install of RetroPie to your KODI set-up, its what I use as I wanted KODI and RetroPie and stumbled across the RetroSMC installer. Problem is then you will need to configure everything. It takes time BUT you WILL have a better understanding of how RetroPie and a PI works and the knowledge of KODI that works

Its a slog at times, but you'll find people will be MUCH more helpful as its then genuine, not somebody selling something that is available for NOTHING, just your time

Have a read through these, if you feel you're upto doing it yourself

By a slog, you'll need to install extra software, then get to understand how to directly access the PI through things like command windows and start to grasp how Linux works

Apart from the Pixel method, @zmanblue could boot a Raspbian installation image from USB. He may have to enable the USB boot mode on his Pi first.

@spud11 I am using the "Filemanager" menu option now. I created a bash script to test how runcommand worked.

But, if as you said, I can create a bash script to invoke joy2key and then mc, I might as well do that.

I did not expect that this kind of change would be so difficult to make :(

@koogelpotato Not without overwriting your existing OS. If you already have Raspbian installed, you don't need to flash the image, you can install RetroPie manually - https://retropie.org.uk/docs/Manual-Installation/.

@affleck001 What was the problem ?

@DougA @quicksilver Thanks!

Thanks guys, it was the case power

@douga Thank you!

I was struggling with the config file saving using lr-atari800. I uninstalled it and installed the regular atari800 emulator. Now the config file works. I also had to set the display to something I could see first. There are presets for the display that work fine.
