I assume you've done a Google search and that none of the listed techniques work?

Was this not an option?...

After looking at this wiki, creating the joystick.xml didn't seem to work and, when I moved on to the official Kodi wiki (http://kodi.wiki/view/keymap) the Keymap Editor Program didn't pick up anything from my controllers despite them being plugged in and working in the EmulationStation interface. A bit further down there was a section about manually modifying some more xml files. I don't understand how I can find the different button numbers.

Thanks again,
Josh

minibian is not supported. Looks like you are missing some of the raspberry pi libraries. I don't see much point putting retropie on top of a Raspbian based distro that is even slimmer than Raspbian Lite (which is what our image is based on), since RetroPie itself will use a fair amount of space etc.

I used ApplePi-Baker to install originally and I also use it to make and restore from all of my backups. I would be surprised if it is causing problems. It still sounds like you're having power issues, but if you have definitively ruled out that scenario, then you probably have a defective Pi. It could have even been damaged sometime after you bought it. Was their any extended period of time when you didn't use a case? Has it always been plugged into a surge protector?

Thanks for all the help guys, decided after experimenting to just stick with horizontal as it displays both pretty well. Here's a wee video of it in action, hope it's ok to share here.

ahhh, just realised i'm using ir-fba for alcon as it doesn't work in ir-fba-next - sorry about that i totally forgot (i'm also using retropie 3.7 fyi).

so it looks like its not going to be possible??

What is in /tmp/runcommand.log after launch ?

you can check the compatibility lists, but lr-mame2003 has decent compatibility vs speed for the RPI3 (and lr-fba-next)

bad guide - you should mount the usb over the existing roms folder. symlinking it may also work (or do a bind mount from existing location).

Changing all the paths in es_systems.cfg is a bad idea.

you need to make sure you mount the drive so that the user pi can write them also. can use uid=1000,guid=1000 mount options for example.

The coco emulator is a coco 1/2 emulator, and doesn't support the coco 3 functions.
The image you are using requires a 512k coco3.

I think we need a little more info before info before we can help you. How are you connecting to the Pi and stuff like that.

Thanks you two. Honestly, you guys are a big help.

@PJROUSE Did you create the file mentioned in the Wiki?
