problems selfbooting wacky races

I dl the game yesterday it works fine with the boot disk. i tried selfbooting the game, evrything went fine, popped it in my dreamcast, sega logo comes up, then the dreamcast menu pops up the one that pops up when there's no disc. Is this game impossible to selfboot or do i need some kinda patch
