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)
-Donkey Kong Jr
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.
