I'm having the most bizarre issue. I'm putting this here but I'm not positive this is the right place so sorry if I'm wrong. I have 2 n3ds XLs and a r4i rts 3ds cart. The thing is, it goes into one perfectly fine but the other one it never clicks in. The system recognises it if I hold it in but it won't stay. Other ds and 3ds games all work fine. I got this system less than a week ago so it has no damage at all. The system it works with has a broken r button so I have no way to play ds games unless I want to buy another new system which is kind of infuriating. Any idea the issue or how to fix it?
