I dunno. If I can remember my DSi LL blocked certain (cheap) flashcarts which worked on DSi. I have intentions to get a 3DS LL but I have no idea whether the present flashcarts work on the 3DS LL/XL system just like on the regular 3DS... tl;dr: Is the compatibility the same? Eg can my current DSTWO work on the XL just like on the regular? Mods move this to the hacking section if needed, because I thought that compatibility has something to do with the hardware.
