Yes, definitely check out the Plailect Wiki! Just note that if you are on an official firmware of 10.6 or higher, you will not be able to hack your system without a copy of Cubic Ninja, Ocarina of Time, or Super Mystery Dungeon for your native console region. Additionally, note that OoT and SMD will require either an Action Replay Powersaves Pro, a regular 3DS at 10.5 or lower firmware, or an already hacked 3DS. The cheapest solution for 10.6+ USA users is typically Ocarina of Time+Powersaves Pro, and don't even need the powersaves pro if they have a friend/sibling to borrow a <=10.5 3DS from.
Anything lower, you can do it all for free, but just make sure you have an SD card with at least 8gb of space or higher. (It's possible on a 4gb, but a lot more tedious than the 3-5 hour process of hacking already is)
