Starfall and CIOSCORP (or a chip) can allow someone to boot an Autoboot Wad Manager disk without even needing a system menu. Granted preloader can load some programs without needing the menu, but it's main focus is for people to be able to boot the HBC in case of a dire emergency. Starfall can save you when that emergency is that you removed the HBC, then bricked your Wii doing something stupid (Think that it can't happen? Well it has on this forum on several occassions). The truth is, each one has benefits, and since they don't overwrite each other, then why not install both.
afaik, Preloader let you boot any dol as soon as your Wii is powered up, so you can directly boot Wad Manager dol if you want
also Starfall patches to system Menu are also available in Preloader, with the exception of the "Rescue Menu" access but it's probably possible to add it in hack.ini also, those are both system menu patches
QUOTEWhat Id like to know, is which one boots higher/first.
