The tomato was QUIRK, the show was the 'power team' which also had kuros from wizards and warriors.

Other shows I recall about gaming. Nick Arcade which had 16bit era games from SNES/GEN/TG16(occasionally), Sparcade which was mentioned, and as you said Gamepro.

Cartoon wise though I remember a shitload:
-Super Mario Super Show
-Super Mario 3
-Super Mario World
-Captain N the Gamemaster
-Legend of Zelda (ran friday on the Mario Super Show)
-Power Team (said it above)
-Pole Position
-PacMan
-Donkey Kong Jr
-Dragon's Lair
-Space Ace
-Q-Bert

I'm sure there is more but that bigass list will do to jog some of your memories. More or less almost everyone of those is from the 80s.
