Help me get my Dreamcast to Read CD-RWs please!!!!

[soundfx4]

Hi, I want to be able to burn Dreamcast games to cd-rws so I can test the game first, and if it doen't work, I don't have a lost disk, because I can just erase it! But I don't know how. I have read the instructions on Dccopyworld, but they don't make any since, there is NOTHING that I am able to turn 1/4 ways clockwise. And there are no screws to take the lens compartment apart to get to anything that should be able to be turned 1/4 clockwise. If someone could actually explain WHERE this so called "pot-meter" also what the hell is it talking about when it says use a multi-meter to ##### if it is between 400-500 ohms? All I know of is an ohm-meter which Im guessing is the same thing, and also, where do you touch the two ends of the ohm-meter to ##### this? Basically, I need MORE detailed instructions on how to do this then given on this website. Thanks
