You're right about Dynamo and Portwind. It fits. Definitely exuberant enough.
Battle! Unknown: What is this based off of? It sounds like a battle with Missingno. or some kind of Rocket Admin, I guess.
Elite Four V2: There are some scratchy noises. Is it my headphones or the song itself? I like Irot's version better, but the gem in your version is from 40-50 seconds, which quite possibly surpasses Irot's, and I'm not a huge fan of 1:02-1:12 for both versions. An arrangement that I'll probably need more contemplating on, but if you could possibly attempt this one again I think you might be onto something.
The other themes you recently mentioned I can't seem to find. Where are they?
