Crazy Taxi boots, but have backgrounds missing

[shadowman]

Hi all, I just turned my non bootable Crazy Taxi into a self boot. The burn was fine, no errors using the selfboot kit. But once into the gameplay...some background layers r missing...so I'm driving in air...with layers of background missing. whats wrong? should I burned the game at a lower speed? I burned it at 4x. it seems some background didn't load properly
