1. Well for version number go on google and find ps2 version guide.
2. Use the search feature.
3. It's possible to do that.
4. To make backups on dvd use dvddecrypter using google.
5. Get a matrix infinity for all the nice features if you can afford it. If you cant get a duo 2 SE. I recommend you send it in to a modder since there is no reliable plug n play modchip. There is a DMS4 EZI but search and Stay away from it.
I hope this helps.
