about GP3 - Expansion Pack 2000

[GameCUBE]

ok, i got both Grand Prix 3 & the Expansion Pack 2000

i installed GP3
now i have tried installing the exp pack 2000 but upon installing it the setup ask for the original GP3 disc which i dont have, i only have a copy

so is there a way around this little security protection ?

i already have the game crack for this but just cant install the exp pack 2000

any help is welcomed on this
