@bifelix89 set the "a" button as your hotkey in emulationstation start menu controller configuration. Just so the hotkey option gets generated. Now open up the file /opt/retropie/configs/all/retroarch/autoconfig/NameOfYourController.cfg . Find the part for exit and hotkey. Assign the number that is your start key to the hotkey and change the exit to another key. (Not b or x as they are used for other options)

@muehltime

are your extensions capitalized? .NES will not work , but .nes will

Capitalized extensions are set to be acceptable in /etc/emulationstation/es_systems.cfg and should work fine. Below is an excerpt from the NES system entry.

<system> <name>nes</name> <fullname>Nintendo Entertainment System</fullname> <path>/home/pi/RetroPie/roms/nes</path> <extension>.7z .nes .zip .7Z .NES .ZIP</extension> <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ nes %ROM%</command> <platform>nes</platform> <theme>nes</theme> </system>

@thewinterdojer Binary, I believe.

I haven't updated at all since March until now, so could be why it took so long. Emulators/Emulationstation/Retroarch etc. only took about 20 minutes to update.

It was just the kernel headers which took a very long time.

@sadtraxx What they meant was that you don't unzip the roms themselves, maybe there was some miscommunication.

The files you're expected to have in the folder must match these:

https://docs.google.com/spreadsheets/u/1/d/1GaqIIoiWbzKHwZ52S2xCSDQXILo81Ls1mHK6czKGAtM/edit?usp=sharing

So, the power source is really such an important point that in no case should not be neglected? And let's say if I want to use an external HD that does not have its own power, then it is desirable to buy a USB hub with its own power supply? But even so, I still can not understand what would be so terrible if the external HD is powered by the pi itself.

@benzine78 dont forget # is a £

@tmntturtlguy yeah that answers it. I was just going to test if i had any issues with some of the same games just in case but you more than answered the question.

@red2blue

Yes it is, because it's supported by every system. But if you got it fixed up, good. But if not, you should try it out with other USB stick instead, so don't yet format your main drive, if it's not going to work in the end.

Thanks guys. Yes - I'm using a Mac to copy over the files. Will use windows from now on.
Thanks again.

I've found a solution:

Install attract frontend, then i can configure my two joypads manually for the frontend.

For the backend(retroarch) i had the next line with value "linuxraw" so i changed it to udev and autoconfig worked!

input_joypad_driver = "udev"

The buttons were previously mapped so only configuring retroarch/all/retroarch.cfg was enough, now the two joypads work.

Hope this post helps someone!

@retrofreak89 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

@joelgbr

(1) Is your Pie on the same network as your computer?

(2) What username and password are you using for WinSCP? It should be username: pi password: raspberry

(3) The Host name on WinSCP should be the IP address of your Pie... (You can find that by using the ShowIP function located in the RetropieConfiguration area...

(4) You can also use a Windows 'file explorer' window to talk to the RP by typing in // IP address (making sure it is recognizing it as a network instruction, and not a website)

(5) Install RetroPieManager (one of my favorite) by following the video below. It lets you access via your webrowser, by putting in the IP address followed by :8000 . It's pretty slick, and let's you know if the files you uploaded are compatible in those folders. Only issue with it is it doesn't quite work well will large files (500mb+)

necrobumping my own post because I found a workaround.
I use runcommand-onstart.sh script (docs : https://github.com/RetroPie/RetroPie-Setup/wiki/Runcommand , my script : https://pastebin.com/XunR2bBY) combined with some delay (hard programmed in my fanControl program) to relaunch fanControl after Mupen has done its shenanigans and thus reclaim the GPIO.

****** SOLVED: *******
In Vice i used "reset settings to defaults" and now Tape-Images are loading!
But i am afraid to say the "save settings" option is not really reliable/stable (i can "save" changes of my settings - but at the next start the changes are gone... Have to check that now....

Thanx @UDb23 and @pjft!
It was the config_save_on_exit = "true" thing that messed it up.
I must have changed that a while back ago when I tried to get hi-scores to be saved.
Got it back to "false" now and the overlays work as intended!

And also thanx for the awesome overlays @UDb23!
