why are there always new versions of the gameshark coming out and why do the old ones become useless for any new games after that?

to make money...?

yer true!! but good way with peepz wid chips in there ps2 except swap magic :D but wid messiah or ne other chips u just download the new version of copy and just upgrade ur old 1!! but ar2 u cant upgrade 2 armax soo its a c~u~n~t init!! i dunno if they done same 2 gameshark! cos am in uk not usa :D

but they might of done gameshark like that2 cos its same company init as armax ;) *codejunkies*
