Help reqd with swap magic disk
 

Hi,
Want to know what exactly is a swap magic card/disk 3.6 and how do you play original PAL game DVD on PS2 console with it? Do I need to do anything like taking making a backup of the game or making an ISO file (don't even know what it is and only read abt it on the forum)?

Is swap magic disk as simple as inserting your original PAL DVD in the console and playing the game or something else needs to be done as well?

Thanks,
Alfa
