Time & Fun : Banana.
The brown one with the little street-sweeper guy.
I also got the Pancake one (I think it was dark green?) later, but Banana was my fave.
At risk of inviting flame wars for wasting TOGgers' valuable time, I found this:
MADrigal's handhelds simulators and downloaded the aforementioned Banana game. That's the end of my productivity today...
