Setting up 4 player games.
In the near future, I will be putting together a list of all the devices I own that are modded. I'll most likely post tutorials here as well. In this picture, we have 2x 2DS XL, 1 2DS and 1 DS Lite. I wanted to see how Call of Duty looked on multiplayer so I backed up my cartridge on all of my DS's. It worked out great but took a lot of caffeine!
My current setup for all of my consoles except for my Nintendo handhelds and the switch. Soon, this shelf will be upgraded!
