ParticipantHi there,
I wanted to give a shot at an old PS1 controller (the one without the analog. sticks).
I connected it to the Pi with the following adapter:
http://www.benryves.com/images/ps2-to-pc/adaptor-product.jpgThe controller is detected by Emulation Station and I can navigate in the menus.
So I exited ES and run the “register RetroArch” command.
There, during the key mapping, when I press a key, nothing happens and I get the timeout, and for each key this is the same story.In the end, it says that the following file has been created:
/media/juliend/retropie/opt/retropie/emulators/retroarch/configs/TwinUSBJoystick.cfgOnly the first 2 lines were filled.
So I copy-pasted the key mapping from a working wired PS3 BigBen controller. I just ignored the analog sticks ones.
I attach the file for reference.
Do you know why the controller is recognized in ES but not by RetroArch ?The strange thing is that RetroArch called the gamepad “Twin USB” itself. So in a way, it has recognized it…

ParticipantHi,
I think I’ve a possible root cause but no clue on how to fix it…
As I said, the adapter with my original PS1 controller is working in ES but cannot be detected as a retroarch controller.
What I noticed is that ES detected in fact 2 controllers although only one was plugged-in the adapter…
As I read in the RetroArch doc, when using the “register controller” feature of retroarch_setup.sh utility, only one controller should be plugged-in. Si if ES detects 2 controllers, I guess RetroArch utility too…
According to you could it be the cause of the issue ?
If so, how can I disable in Linux the “ghost” controller ?
