and if i can how do i do it to make it work on the playstaion 2?
i know i must sound such a newb at this >//< But i will be grateful for your help ^^

If your ps2 is modded (mod chip) then it could play them, no idea if the non evasive "swap disc" method works.And ps1 games (psx-ps1=original playstation games) go on CD's unlike ps2 games which are in most cases burnt on dvd's.And we all start somewhere, I know how you feel :)

thanks >//< you're awesome...

If you're going to be playing PSX games on a PS2, then you need a swap disc.
I own a set for PS2 games only, but have never tried the PSX swap discs.Here is an example of the PSX swap discs. - http://www.modchip.ca/store/product.php?productid=16193&cat=256&page=1
