I'll fix that up - something must have changed the logic in bash as it's fine on my ubuntu desktop and on raspbian. Maybe a specific version of bash has some different behaviour, but the variable should be initialised so I will do that.

It's not available for the rpi3. X86/X86_64 only.

ok, after 2 days, I finally solved the problem..by default steam stores, the file /lib/udev/rules.d/99-steam-controller-perms.rules

for some reason the retropie script also installs /ect/udev/rules.d/99-steam-controller-perms.rules

the file in /ect contained the instructions for xbox and keyboard which was overridding the /lib rules.
I removed the ect file which should not be there and everything is now working. (I actually removed both files and reinstalled steam-devices)

I had the same problem,where the hell is Doom then I realized that it not installed,its to make the image smaller so it don't take long to download.

If its working fine in 3.4 and not working in newer versions of RetroPie then its a bug. Report it as a bug and see if anyone can fix it.

@kAnGeL88 Those emulators won't run on the current Pi hardware, so theyre not available on those builds.

@Flipcrazy You can use as many as you want. Just follow my guide here

But beware this is not the officially supported way of doing it.

@dankcushions

@Slighty sounds like a corrupted SD if you have the funds to secure a pi 3 I'd recommend it. Very happy with mine compared to the pi2.

ok, I see it under ports but it doesn't do anything when I tap it.

@giles2005 said in Retropie portable gpio controls problem.:

iv now solved the problem anyway. would have been nice to share the solution as a means to help others but nevermind

Before you share the solution to "the problem", you should tell us what "the problem" actually is!!?? You still have not done this. Currently, your problem is still "my project"does not work! Bizarre. I shall assume from your username that you were born back in 2005 and it shows.

The error above happens I believe when the ps3controller driver is installed as the standard bluetooth daemon is disabled. The isue may be an update to the ps3controller driver which was in place for a day which had a bug. Try updating retropie-setup and removing/re-installing the ps3controller driver and repairing.

OK here are two brand new tests, with the exact settings and steps I am using:

Exited Emulationstation and tried the scraper with default settings and it still didnt do anything- it instantly says complete.

I then deleted the gamelists from both folders whilst emulationstation was closed.

Ran the scraper in emulationstation again and this time it outputted a file which I could use. The only difference I did this time was made sure emulationstation was closed when I deleted the files- I thought I had done that before but maybe I hadnt and that was the difference.

Weird that it doesnt work outside of emulationstation just for the SNES and weird that it just worked this time- I had tried for 2hours constantly trying different settings/combinations of trying to do it before. No idea why it worked this time but it worked so I'm happy now!

Thanks for your advice
