hey, go ahead and do the ultimate, it's fine, as long as you do the rest in order, then link back to your final update of White when you're done with the rest. Alternatively, you can pause your White challenge, do the other generations, then finish White in it's proper place. AND one more thing, you don't have to do FireRed, since Steel is not in Gen I, for an ultimate. You can start with Johto.
