any non paltinum version works, older platinum versions also work, new ones dont, anythign you buy in a store now is probably gonna be the patched one, you cna check a used game store maybe, try to find a non-plat
there is a way to tell teh working plats from non-working, it has to do with the serial numbers, its in someones sig, but i cant find it at the moment
yo umight also want to consider mechassault or splinter cell, although MA is patched now to, splinter cell will work with any version
