I want to install some homebrew to: avoid bricking & the possibility to back the system up in case I do brick in the future & the possibility to roll back updates. I've been suggested Preloader, which looks nice. But BootMii also looks nice. Which do I install? Either? Both? Bonus question: Any specific IOS I need to install if I want to play newer games but don't want to update from 3.2? (Eg. Kororinpa 2 doesn't boot, shows black screen, I've been told it's missing some IOS) Thanks!
