@edmaul69 actually i ruled that possibility out, but it seems your guess was partly correct. My RPi2 only need 2A, but i forgot that DAC+ sitting on the PI. So when i removed it i no longer had the issue of ghost input. So thanks for that! I still have some controller issues regarding moonlight, but this is maybe the wrong place to solve them.
Thank you again
I just created the script to make things easier to install and setup Moonlight-Embedded. I have just updated this script today BTW to include a new menu based structure for an even easier solution. In regards to the controller mapping, this is now all stored in a txt file within the Moonlight program. It's called gamecontrollerdb.txt and contains the mapping for over 100 different gamepads. Here's what I could see in that file:
Maybe it is also an issue with the power supply: If you are using additional USB devices your power supply or micro USB cable might be components to exchange. We had this often with other installations in the past.
I would also be quite interested to hear people's opinions and experience with this. The advanced controller mapping guide is excellent and very comprehensive for xboxdrv however the retropie wiki does seem to suggest xpad is the preferred and is even the default.
I would especially be interested if anyone has any suggestions for xpad tweaks to improve ScummVM analog control.
Thanks Gerald. This worked for me! I'm assuming I'll have to do this for every additional controller I have connected, but it's not a big deal. I wonder why the main Configure Input on the emulation station doesn't work for the individual roms.
