Hi! So i've been hacking animal crossing new leaf every once in awhile when i wanted a specific layout for my town, The last time i used it was with soundhax after that i stopped playing my 3ds for a bit and accidentally updated to 11.8 firmware. I was looking around for some time and someone suggested CFW to me, and that i can use it to hack ACNL without worrying about firmware updates, My thing is im still not entirely sure what it is, how i get it without having to buy that weird cartridge thing (i have 3 ds cartridges with actual games but im not sure thats what that weird thing is for lol) , and that stuff. I was hoping i could get some more information? I dont really mind if my 3ds gets like a online ban or something since i dont really have many games for it except nintendogs, 2 copies of ACNL and such, But i really really want to get back into ACNL, and to do that i have to do alot of town re-arranging due to poor villager placement.
