Re HALO Hack!
The HALO Hack (trainer) DOES work!
To have HALO and HALO Hacked available, take a copy of the HALO default.xbe, patch it, rename it, copy it to the HALO directory and create a link to it in the EvoX menu.
Press both thumbsticks to access the cheats menu - turn on features such as infinite ammo, never die, jump really high, etc
Fun additions for a great game.
