Which one?

iPod Video click wheel games. Specifically Mini Golf. I've also been working on an emulator for the others and it can now boot all of the 20 decrypted games released ~20 years ago and play most of them. There's a Sims Bowling, Sims Pool, and Lost game in there which is cool from a preservation standpoint. Less cool are the SAT Prep 2008 games which have actually been surprisingly annoying to emulate due to the way the text uses blend modes.

I plan on releasing all of this at one point. It's crazy it hasn't been done in 20 years!
