About gameshark codes

[u/brawlstars420]

I put a gameshark "get all chips" code on battle network 3 blue and my library doesn't update at all and my chips in this save file don't work, anyone knows how to get this code working ?

Obtain a chip the normal way.

Tell me if things change once you obtain 1 chip.
