Hi

Thanks for your reply.
Haven’t had time to go back to the problem in the past week.
I’m not using a Pi2, so I don’t know if the update you mention should make any difference (on my Pi B).

I’ll try a fresh “installation” of the retropie image and only configure snesdev to see if it works fine. If it does, I’ll start configuring things one by one and checking if the button works each time. This in case somehow something I configured is what caused the issues with snesdev (seems unlikely, but I’ll try anyways).

I’ll keep you guys posted.

Edit:
Ok. With a clean image installation it works fine.
I’ll still check if it keeps working after every different configuration I do in case the issue arises again.
