rent or borrow a real wave 4 game and update your dashboard, then before you burn your game patch it with

to a wave your 360 can handle.

but big warning if your xbox is connected to live with a patched game you WILL get banned.
i'm banned already so makes no difference to me and works perfectly but if you want to even connect your console to live then pay for the firmware update but as far as i know most of the firmwares for drives that support wave 4 games are in development so this unless your lucky enough to have the right drive the method i described is the only way to play.

 

i buy them not burn them

 

if your buying pre-burnt ones then you will either need to contact the seller to see if he can patch it down for you or rip it to your pc then burn it back off after patching
