I think it is more likely that the act of taking the cartridge out and reinserting scrapes away at grime that is stuck on the pins, creating better contact with the connector in the console. Blowing into them likely did nothing.

Haven't heard anyone say chelatchie out loud before, but I live in the pnw and I would guess it would be pronounced cheh-latch-ee, which is similar to how "Wenatchee", a pnw city, is pronounced (not helpful but interesting nonetheless).
