If you use link with the latest address, you have to patch all versions to point to the latest, otherwise you can just patch the first. Advantage of using the latest address: one saved jmp per call.

Surely you need to patch *all* functions, not just the initial? The point is with the current solution no matter which version of the function another function is linked to, it will hit a sled of JMPs and eventually end up at the newest. If you only patched the first, that sled wouldn't work. So you'd have to patch all instances. That still shouldn't be too hard. Cheers, James
