saturn screwdriver trick

I read the faq on how to change the laser strength to read a cd-r and I tried to get it to work and it won't and I don't understand what I am doing wrong. I have a type 2 sega saturn is there any kind of special eqipment that I need to get this to work?

Thanks in advance
You did mean a CDRW and not a CDR, right?

But do make sure your CDRW disc is properly burned/will work, and if your Saturn won't read it, just increase the laser strength a little more... until it kicks in. Best to make sure your Saturn still reads normal CDR discs as well.

To make things easier, you might burn a normal audio CD to a CDRW disc and just try to make your Saturn play the audio from the BIOS menu.
And be sure to don't set it too high or your Saturn will overheat and games will start to have problems (like freezing). I know that cause it happened with me
I would just stick with CD-R's but if you want to tamper with your laser it can be done
Check the guides here.
Well, I adjusted my Saturn to use RW's, and it didn't take me long as all.

I adjusted the knob one way... untill it stopped reading any CD's.... so.. I uh, turned it the other way.. untill RW's spun up, it can read RW's fine now.. only took me about 15 mins to do.

Took me 3 1/2 hours to do it on my DC.. it is FARRR more picky, as there is a "sweet" spot you must find. >_<
