@Subs, I was more referring to the steps one must follow : first connect, then eventually map and finally configure. Sometimes BT pairing does not work, sometimes controllers are detected as PS3 controllers and you have no clue on what's happening and how to fix things. Plus Forget Bluetooth Controllers seems to not work. Anyway I'm sure that if everything does not work straight from the beginning you struggle like I did to find a solution. Just see posts in this forum to have an idea of what I am talking about. My idea is rather simple: I suggest a wizard, assistant, you name it, within the system that take you by the hand, explains you what to do. It's just an idea. Other than that I must say that recalbox is very well done and easy to understand and configure. Great job guys! perezsy

Thanks @subs! Indeed second controller needed to be started with Start+R. But even with that it did not work the first time. I had to reconfigure first controller again and I discover that the "configure controller" menu displays what controller ID it is configuring (Gamepad 1 or Gamepad 2). That's crazy! I was configuring again first controller while I expected I was configuring second controller! Bluetooth controller configuration for recalbox is really painful all the rest is great. I wish there was a more user friendly way for configuring bluetooth controllers. Maybe a new feature should be a step by step assistant with detailed instructions. This would help a lot. Anyway thank so much for your help.   perezsy

@paradadf Hi, I also have two NES30 and managed to pair and configure both. Unfortunately the two controllers acts as Player #1. I mean when I enter a game I can play as Player #1 with the two controllers. There is not Player #2. I configured P1 as Wireless Blueetooth Controller #0 and <span style="line-height: 1.5;"> </span><span style="line-height: 1.5;">P2 as Wireless Blueetooth Controller #1, but it did not helped. By the way, both controllers are started using only the Start button.</span> Can you please share with us how you managed your configuration for 2 players? Thank you.
