We recommend this modification for ps2 slim users who cannot install the magic keys2 or for those who want to use the magic swap more easily. We modify the sensors from the original lid of your play so you don't have any setbacks when using your magic swap. Simply the play will no longer detect when you open the lid and you can easily change the discs without any visible modification. Also weld on the base plate a diode protection so that your lens does not suffer when you use backups. Also remember that it is elemental that you record backups in good quality dvds and at a low speed. IMPORTANT: When you have to open the console, the manufacturer's warranty will be void. This service does not include any charging disks.
