Freaky!
I see a command in the button config for "speedup cheat" but it says none and won't let me assign a button to it!
The speedup for Jr. is not a cheat. By default button 1 will speedup both Jr. and ghosts. If you enable that cheat you essentially reverse button 1. That way you go really fast UNLESS you press the button, rather than really fast WHEN you press the button. I HIGHLY recommend enabling that "cheat" because as you get used to controlling the little guy in hyper mode you won't want to have to keep your finger on the button the whole time.
Something I found funny was the "fruit" once you get to one of the levels...
trike,kite,drum,balloon,train,kitty,beer?
It might be a rootbeer float, but it looks like a nice glass of beer.
