[badblu]

Hi

This may be a stupid question my friend has an xbox and has a chip i am not sure which one but he dosent hav a dash installed it just loads up the games.

My question is do you need to patch a game which has media check on it or will it still work if i do a backup the game is NBA Live 2004.

The game works fine on mine but i am not sure if it will work on his.
