Play Cracked Games Online?

I remember back in the day I used some program to play cracked games through a VLAN, but I can’t for the life of me remember what it was called. I have the urge to play some Star Wars Battlefront II online. What would be the best program to do this (with an active community)?
Answer #1
Hamachi works if you know who your going to play with and G Arena for the community type. You’ll need LAN support for the game though
