How to Download and Burn PS2 Games:

For this your PS2 has to be modded either by a modchip, swap magic or memory card exploit. If it is, then you're good to go!

Where to Download The PS2 Games:

To download PS2 games go to http://www.ps3iso.com/ and head over to PS2 Game Downloads.
Download the Game of your choice.
OR you can download the PS2 games
using torrents. Just download Utorrent and head over to a torrent site and download your game.

What to do after the download has finished:

If your game has multiple parts or .rar file then you need to extract these. Just right click on the first .rar file and click Extract Files. Select where you want to extract.
After extraction you will see only one file that will be the ISO file. This is the file that you want to burn.

OR Some downloads do not contain multiple .rar files, they just contain the .ISO file. Then in that case you don't need to extract!!

How To Burn The ISO Files:

To Burn the ISO files you will need a blank DVD-R (DVD+R also works). Buy a blank DVD that is of first class (made by SONY or Verbatim or Fujitsu) or if you use other local brands or third class media then they might not work (but  I will post on how to make the third class media work on the PS2).

To Burn the ISO I highly recommend DVD Decrypter OR PowerISO.

Download DVD Decrypter here:
http://www.dvddecrypter.org.uk/

Download PowerISO here:
http://www.poweriso.com/download.htm

Insert your blank DVD, open PowerISO or DVD Decrypter and burn the ISO File( I used PowerISO).
After Burning the DVD, insert it into your PS2 and play with any of your modding technique.
ENJOY!!
