I was considering picking up a DSi XL or 3DS to jailbreak (because I don't want to jailbreak my 3DS XL), and I found offers for both (used) at 40 EUR for the DSi XL and 65 EUR for the 3DS. Firstly; can you create games for a homebrewed DSi XL or 3DS? - If yes, how? what programming language? useful tools? Secondly; does the DSi XL have any (other) benefits over the 3DS (such as it being larger) or vice versa?
