I accidentally left some games in my pocket while I was at the beach. They wouldn't work at all at first, but I put them in some rice to dry them out. They run now, but sometimes they stop working after an hour or so (and in one of them there are some glitches). So rice helps, but I'm still working on a better way.
Looking for the same answer...my son let 3 games get wet in his pocket at the beach today...ugh
