Hi how to burn a downloaded ps2 game into a dvd so

Unfortunately, you cannot do this without doing a major modification of your PS2 or getting a a commercial grade PS2 burner for your computer.

The issue is that unlike regular DVD's, PS2 DVD Games spin counter-clockwise, therefore you need the games to be burned, counter clockwise.

A couple of years ago there were people out there selling modified PS2's and kits so you could modify your PS2 to play games burned clockwise. Do a google search and you may find them still.
