Does this store (or any other Gamestop) do repairs for more older consoles, or consoles in general? I have a DS lite that I've been wanting to get the D-Pad fixed, and I'm trying to find a shop that would get it fixed.

I'd try Gamers

They don't repair them, but they will take broken systems in on credit towards anything else in the store.

Yup, this is beyond what GameStop does. You might get a recommendation by stopping in and chatting with their people - everyone is knowledgeable and super friendly.
