first, I don't remember ANY promotions for TG-16. Sad, but true. But...
Dude, I've emailed Jim Hakola -- it was... 1-2 years ago! Before the TurboPlay Archives existed, if you searched for "TurboPlay Magazine" or "TurboGrafx Magazine" in google, guess who's website would pop up?
JIM HAKOLA's!
He makes (made) small plastic / vinyl figurines (his own original designs) and he fashioned metal jewelry as well (video game inspired trinkets, of course!)
Anyway, he had a random page (non-business) that documented his high-scores!!!
We exchanged 1-2 emails, but I don't think I got a chance to tell him where I live now
I sent him scans of the TurboPlay Contests he won, of course.
