If not at sound go round try robot City in Binghamton. That all i got, hope its helpfull
If they don't have it, i would be surprised... They have everything. Call first they can tell you
They have a very wide selection of games for all systems, Gamecube included! The prices are fairly reasonable but if it's a popular or rare title the prices can certainly get up there. Do your research and definitely check them out.
Not sure of the exact prices But sound go round is sure to have them at a decent price
