Wireless Controller(s) with Picade Console

Hey guys,

I played with a retro gaming machine for the first time last weekend, and I need to have one!

I love the idea of the Picade console and decided this is going to be my first project. As the Picade is equipped with controls for 1 player only, I’m wondering if and how I can play with 2 or more players. This question has 2 aspects:

  1. Does Retropie support multiple players at a time, e.g. for games like Mario Cart? If yes, is there a limit or does it solely depend on the game?
  2. Can I use the Picade console with multiple players using remote game pads? I guess I would prefer not using the built-in controls at all when playing with 2 or more persons. Can I adjust the respective settings in the Retropie menu? Do I need any additional hardware to connect 2+ remote game pads? Do they just have to support Bluetooth? Any specific recommendations when it comes to the pads?

Thanks for your help,
