honestly, all you really need is an exploit with access to homebrew launcher if this is all you want. Just get menuhax, get HANS running, and thats all you really need you dont need A9LH unless you plan on doing more complicated stuff with CFW like directly installing and downloading games, Better emulators, nand backups, etc.
every time i see someone suggesting a9lh for something this minor, i think of someone going into a car shop for a flat tire and having the mechanic suggest you install nitrous into the car.
