TI99/4a legend, Rasmus Moustgaard, is working on a pinball game for the system. It's currently in beta but you can download an early version from here.

From what we can see already Pinball 99 looks pretty complete, and features music and synthesised speech. Rasmus says he doesn't have access to hardware at the moment, so is interested in knowing how it works on the real deal. (Pinball Dreams fans may recognise that the table is based on the Ignition table)

You can see a video of the game in action below.
