So for some weird reason the only button remapper that's worked for me has been the first one made, B <> A and none of the others work.
I want to change L to D-Left but the one posted here (cesarpk) and all similar versions (Brongus+AlmostBadKoala, SirKyogre_Left, SurpriseTridoron) don't seem to work for some reason. It'll say that it was injected but won't work, even if I turn the 3DS off and on and try it again.
I'm using a New 3DS if that's an issue? I don't think I've done anything wrong, I've just moved the .cia onto my 3DS, installed it via FBI and opened up the software and let it run, closing it with start as it asks.
Although now that I've tried to install other cia's my 3DS doesn't want to put them on the home menu....
