Leesie. Sorry for tagging on but I'm a Newbie as well and am at a similar point of installing. I have Homebrew and BootMii installed and have made a NAND backup.
The Real Jdbye said you should get ModMii. If I understand correctly that is an interface that you can use to install other things. Can I install that now that I've already installed Homebrew and bootmii, and use it to install everything else such as Priiloader, etc.? Or, should I just download priiloader and keep going the way I have been, installing one thing at a time. I know PriiLoader will help me from getting bricked, so probably good to have even though bootmii is on boot2. After PriiLoader I'm not sure what I really need. I don't want to install anything I won't really use. It looks like there are USB and Disk Loaders, WAD Managers, and CIOS...and probably other things I'm missing.I just want to be able to download Mario Kart races and any anything else Mario Kart. Can someone help?
