I took everything apart and cleaned all the contacts on the wires, it now seems to work ok, thanks for the help guys

@rkoster

Raph,

thank you so much for your patience and kind support. I really admire guys (of course people in general) who help others and care about things without any material or commercial background. I'll try to to my best to behave like this in the physical world (but I suppose you, too ;-))

I'll stick to your website and your posts and hope that we will hear from each other once in a while. I will keep reading about linux, the Atari Emulator scene and feel really good about what is happening these days with this bunch of possiblities I always dreamed of and which really came to life. I'm so thankful for this. At the end of the month I will visit old friends and we're having a Midimaze party (Midi Network Game for the Atari ST) like in the old days, I will present my MISTer unit and the GPI case and will tell people about your Atari graphics post for the Retropie Project.

I'll be in the country over the weekend here in Brandenburg and hope that you and your familiy will have a great weekend, too!

Again, thank you so much for everything

Best wishes, Joern

As @mitu said. The reason behind it is that the mappings are stored under the name of the controller in the directory /opt/retropie/configs/all/retroarch/autoconfig/. Thus, if you have identical controllers, only one mapping will be stored for both of them, and if their wiring is different, their common mapping won't fit one of them.

edit: "will be" -> "are" + "doesn't" -> "won't" 😉

@simotsu I figured it out... After reading this forum a little bit I found that I had it wired incorrectly. So off to the races now!

And thanks that you shared it for others.
