Hi firstly you will either need a modchip or have had a "softmod" done which flashes the xboxes onboard bios. Then after you have the xbox modded you will need to install your chosen dashboard be it Evo-X,Avalunch,UnleashX, ect ect. Most of these dashes should then have a tool included that will allow you to save games discs "one you own of course " to the xbox Hard drive. It must be also mentioned that it would be wise to add a larger Hard Drive to the xbox of approx 120gig in size as the standard xbox Hard Drive is only approx 8 to 10Gig in Size which after its all modded you "might" be able to save two games to it. So a larger unit would be required. I have a few maxtor maxline II's of 300GIG in size for all my stuff. Regards
