Prepare buying a third-party controller converter https://www.mod3dscard.com/home/22-coov-… for using my PS4 joypad on the Switch, will it be a hurt to my console?
It shouldn’t. I don’t know about that adapter, but this one https://smile.amazon.com/gp/product/B079… works just fine for me and I’ve got a few friends that also use it. This one is also cheaper and allows you to use the DualShock 4’s Gyro with games like Splatoon 2.
