WTB: Phantasy Star for SMS

[icbrkr]

I found Phantasy Star for the SMS a few weeks back, and started to play it - now I'm hopeless addicted :) The wife, however, was watching me play and she started playing as well. This creates a dillema for me - we can't both play at the same time! So, now I'm looking for another cart (loose, don't care about the whole thing) so I can play it on my Game Gear when she's hogging the TV. Anyone?
