EDIT: READ THIS BEFORE REPLYING! If you are going to reply just with "no" or "Just buy a second controller" then get out because "no" without any explanation why is just lazy (and it IS possible, just look at how someone connected a GameCube controller to 3DS without hardmodding it and without any wires), and buying a second controller doesn't appeal to me either because I've decided that it'd be interesting to connect any controller via WiFi and bluetooth. For now hardmodding console isn't an option here (it was done many times and it's uncomfortable and permament with risk of destroying the console or you need to pay a lot of money for it). By the way, I don't want to force any developer to work on this project. Most likely I'll try to do something myself. And it's just an idea, a project, not something that developers must do. I know that most of you will just type "No" because 3DS doesn't have bluetooth, but I've got an idea. I'd require a PC, hacked 3DS and a bluetooth and infrared adapter to work. My idea is that the Wii Remote would connect to the PC via Bluetooth adapter and then the inputs from the Wii Remote would be transferred through some software to the infrared adapter, which would transfer that data to some homebrew software on the 3DS, because 3DS has an infrared port. Is it possible? EDIT: From now on the infrared concept is digged. It should use WiFi because WiFi is faster and you don't need to buy an infrared adapter. And it's probably easier to code. I'm so dumb that I haven't thinked about WiFi before. EDIT: Actually we can use ANY controller that doesn't require wires to the 3DS with the technique that I've written above.
