For some reason everyone calls OOT a secondary exploit. It is true that you need to buy something that you'll never use again (a Powersaves) to run the exploit. But it is also true that Freakyhax means you need to buy something that you'll never use again (Freakyforms Deluxe). Why does it matter whether it's "have to buy exploit game" or "have to buy exploit game + device"? Wouldn't a more useful definition of "primary exploit" mean "an exploit which doesn't need another hack to install the exploit"? If you use that definition, then OOT is a primary exploit, because all you need to do is buy something, just like all you need to do is buy Freakyforms or Cubic Ninja. In this connection, https://www.3dbrew.org/wiki/Homebrew_Exploits defines "secondary exploits" as "Installation of these exploits requires a previously exploited system to install." By this definition, OOT is a primary exploit, since a Powersaves is not a previously exploited system. Nevertheless, it lists OOT as secondary.
