I don't know how it works on a slim, but it's possible.
on a slim, you need to block 2 sensors. one is above the power button (you can take some paper and and stick it in there and put tape on it. the other sensor is inside the ps2. there are a couple of methods to do this
straw method
tape and tissue method
personally the straw method was very hard for me to achieve. if you dont want to take apart the console, the tape and tissue method is out of the question.
using the straw method makes it not able to close (or atleast i didnt).
there is another component that needs to block, and thats the disc stopper. there is a little hole in the corner of the right side of the tray, you needs to stick something in there to make the thing unlocked (ie, not stopping the disc). i used to use a cue tip, and that really will make it not able to close anymore.
honestly, it made my ps2 ugly. the flip top was always up, there was a straw stuck in there, a que tip sticking out, and another que tip inside the hole above the power switch, and alot of electrical tape. the things i did for swapping without buying swapmagic tools :\
when i attempted to do the tape and tissue method i opened it up and broke the power button so i had to turn on with the remote lol.
by the time i got a new power switch, the cable that hooks up to the power switch was broken, could not find a long one for my model (the 79000 cable is aperrently rare, and everything is up to 79000 on ebay at that time), and the other cabels are about the third of the size, so i had my ps2 on without a lid for the longest time until the guy who i sent my ps2 fixed everything. though the 3rd party switch wont work with the remote which is unfortunate, especially because he soldered the the thing with wires to the mobo and im not risking fucking up my ps2 again.
anyways my advice: get freemcboot, use ESR. no swapping, no blocking sensors, no nothing. either that or get a modchip. both are just burn + play.
edit: please note that just because i fucked up and didnt do the sensor blocking right, does not mean you will fuck up your ps2 like i had.
just please be careful when you open your ps2. not just the op (since we dont know if he has fat/slim), but anyone reading this, if you attempt to do the tape and tissue method. *please*.
