when you're submitting to two jams at once there's currently no way to choose which banner appears on the top of the page. It does show all jams submitted to on the top right of the page though. Sorry :(.
I thought that might be the case. Somehow it shows the demakejam game now though, so it's automagically solved :p Edit: Oh now it's the gbjam again, oh well, if they keep switching around that's fine too :)
