Diz.mx - now that it's all clear that you need to mod the PS2, here's the standard advice I dish out to help people who are new to the question.

I provided the below comprehensive reply to two other people over the past two days. You will need a modchip for your PS2, copying software and the right PC hardware for the job. I recommend the Yamaha 2100S (or E) CD-RW for optimum caompatibility for read and write with the recommended copying software.

Go to http://www.megagames.com and http://www.psxcopyworld.co.uk to get detailed advice. The basic principles are as follows:
1/
You will need to get the PS2 chipped to allow backups to play. Go to the website http://www.playstationmods.com from where you can buy a mod. An internal mod is recommended and if you live in the UK, they'll do it for you if you are not a soldering whizzo.

2/
You will then need copying software and patching software. I recommend just two programs: they are CLONECD and CDR-WIN. The former makes 1:1 copies (you'll need the tutorial from one of the above mentioned sites). Thus if you have an unprotected game (megagames.com lists games for which there are patches and the type of patch required) and if the game is of the same denomination as your PS2 (e.g. PAL), CLONECD does the job perfectly. CDR-WIN stages the CD copy to your PC's hard disk so that you can patch the game as necessary (per PPF-O-MATIC.EXE downloaded from megagames.com together with the patches); then you burn the game back to the CD with CDR-Win.

3/
For the above to work properly, your CD-R MUST be compatible with the burning programs. The sites from which you download the programs list the compatible devices.

4/
If you copy games from one TV standard (like NTSC) to play on another standard (like PAL) then the game may or may not play in colour. There are patches to change this or you could buy a convertor that sits between your TV and the PS2. I have one of these because I hate patching and the patches don't always work.

5/
Your biggest challenges will be DVD games and Protected Games. DVD games can't be easily backed up at present (search this forum under the keyword DVD RIP). Protected games are likely to be an increasing issue. Megagames.com is usually on the ball here but for EA games, go to http://www.eapatcher.com

This forum has nearly 18,000 subscribers. I'd bet that the bulk of them started off like you. It's not that difficult when you've done it once, especially with CloneCD.

Good luck and I hope this reply has been helpful.
