Got any NES games?

Handheld NES console called the Retro Mini actually plays NES cartridges. Funny that the entire console including screen is smaller than the cartridges.

The question is: how much blowing into the cartridge or the unit do you have to do?

I know it's much less legit (not at all, really), but I recently sent a little money to Hong Kong to get one of these. It rocks.
