Yes, I'm native. If you mean I was born in Belgium . I'm from the Flemish part of Belgium (dutch speaking).
Extra info: Belgium is divided in 2 parts: Vlaanderen (dutch speaking) and Wallonie (french speaking). Also a little German speaking part, but that part belongs to Wallonie. This situation give lots of problems nowadays. At the moment we don't even have a government (day 155 of the crisis): lots of discussion between Vlaanderen & Wallonie. This discussion might be the beginning of the end of Belgium.

What do you mean with "caches"?
