Meh, I'll just recommend goign through the game the way it is right now. The placement for most pokémons now makes sense (most of them), and too many cool changes to go back.
But as we always say, we can't stop you from going back. Unfortunately, I myself can't help since I don't have the links... anymore.
As a tip though, be mindful of past event and such. Certain locations were removed, and errors are expected. And certain pokémons will have their locations marked as "REMOVED" in episode 15 onwards.
If you want an episode to start, start at episode 1. So you can get Volt Switch and Spinda's running around the Opal Ward imeanwhat
Jk... the chances of finding the original episode 1 is minimal, anyway~
