Interesting anecdote regarding the most recent episode of Basquash!:
Paraphrased from Catsuka.com
The ball-in-cockpit control is an error. There’s indeed a special dribbling controller but it’s a sort of giant trackball. Episode 5 was outsourced to a not-so-good studio and they didn’t understand the controller thing, drawing an actual basketball instead. When Satelight discovered the error it was already too late. Especially since 4 was outsourced too, and came back so crappy they had to redraw almost all of it, thus not having time to correct 5. The DVD version will have the right controller.
