hello... i remember seeing a workaround for getting apps and games to scale correctly even when they were not developed for the larger screens.. it had to do with the Spare Parts app... Not sure if rooting was necessary or if you could do this with the stock tablet. Also not sure where I read this but maybe try searching google for the workaround?
I have the galaxy tab 10.1 btw... By the way, i thought spider man was supposed to work on 10" screens? Gameloft site said it was compatible with my device.. Hmm... thats weird... Good luck...
