By needing an HM, I guess I wasn't clear. I meant needing an HM that you don't have access to at the moment. Like serebii will tell you that, for example, in R/S there is a TM for Dragon Claw in Meteor Falls, but it doesn't mention that you need HM Waterfall to get it.
You can search forever in Meteor Falls, but until you have that 8th badge you can't get the TM, and by then your pokemon are at high levels, making it less useful. That stuff obv. gets accounted for on in-game lists.
