i am recently trying to buy a swap magic disc and gathering info about it. Yesterday i got an email from a site that i have to get a fliptop because the PS2 slim's fliptop wont work, so i have to get the fliptop with the disc. But i have seen videos on youtube where people just covered the sensors and used disc and it worked and nobody used a fliptop. so i am in a fix if i need it or not.
