I'm just saying that if you don't use the 3D function of the 3DS, then you won't get headaches. But having a 3DS and not using the 3D function is pretty pointless to begin with... Basically, to play 3DS games without 3D rendering, turn off the 3D function (pretty pointless to keep your 3DS imo); to play regular DS games you could use a 3DS (turns off 3D rendering by default)/DSi/DsLite/or DS. There just isn't a market for this fugly inelegant "2DS". I'm not claiming to know anything about your life because simply, idgaf, but I will say that Nintendo has just given us their most recent flop...
