Hey guys so a while back I got a Supercard DSTWO for my 3DS XL but most of the time I always get this error "An error has occurred press and hold the POWER button to turn the system off. Please refer to the operations manual for details" on my 3DS XL. Now idk if its the cartridge or the 3DS (XL) but it works like 1/8 times but I always have to blow in the slot for it to work now idk if its the cartridge but I noticed there's a little screw on the back, maybe if I tighten it it might help? But I'm asking am I the only one or is anyone else having this problem? I need to know did I get a lemon or is there a fix for this thanks.
