I was recently researching some of Tecmo's older arcade games, and ran across a soundtrack for a 1995 title "Ganbare Ginkun". The CD had Doodles on the cover of and throughout the booklet, some with spears, some with glasses, etc. Anyway, it appears that this game-show style arcade game was their very first appearance, and while I have never seen an actual machine, I have seen enough evidence to be convncing. Here's a link to pictures at The Video Game Museum but beware of popups, especially ones asking if it's ok for something to download onto your computer (say no to that).

hahahaha
This is a game i'd love to have played. heh
