* The file already exsists, otherwise we wouldn't have gotten
this far in the boot.
* We have already checked if it's a Wii or GameCube elf,
besides, it's too late to change our minds now anyway.
* On Wii - Don't call EmulatedBS2, it can never succeed as
it knows nothing about booting elfs. Just call the
SetupWiiMemory directly if needed.
* On GameCube - We still call EmulatedBS2_GC, but we stop
it from running Apploader, which might boot something
unexpected from the default iso or DVD root folder.
