So guys I have had my DS for a long while and have been meaning to upgrade for a bit now, but I'm wondering, how easy is it to mod, is it safe, and what version of the 3DS should I get, or just get a 2DS instead. What would I need to play 3DS ROMs or CIAs or whatever they're called, an SD card? Should I buy a new or used DS? And I have an R4 and AceKard 2i, but I use the AceKard and I'm wondering if that'll work on a hacked 3/2DS because I know that on a normal one it won't, for either of my cards. That's it I think, any help is appreciated.
