Where do i swap discs... ive tried everything possible. thanks

both discs are bootable... load disc 1 if you want to play courses 1-3, and load disc 2 if you want to play courses 4-5 and short course... if in the middle of the game, you can just eject and swap the discs when you're at the main menu where you select the type of game (single or multiplayer etc), or even at the menu when you are selecting the course you want to play

must be a bad burn....
