Hey bro, welcome to the forums here! As for your questions, I'll try my best... even though I'm no expert.
Ok since im new to the ps2 "hacking" seen what exactly do you need im hearing from dif places you need a mod chip some say you do not idk.
You can either use a Mod Chip or most people use Swap Magic 3 with either a modified Flip top lid (most places online that sell the Swap Magic Disks might include a
PS2 Flip Top for an additional $10 or so) or a set of Magic Switches (also called Magic Keys) to trick the
PS2 into thinking it is closed so you can swap out a disk. More info here:

I don't think so, but if you look at the Tutorials sections then maybe you could find something. I haven't done so, I'm happy with Swap Magic, but I guess others have.
http://www.ps2iso.net/index.php?board=12.0 Now the final question is do you need a dvd burner to have games.
YES. You will need a DVD burner because the games are DVD based. I recommend DVD+R. Most brands will work fine as long as they aren't cheap-o brands or DVD Media made for movies. I use MagicISO to burn games and it has worked flawlessly for me. Other have used Alcohol 120% and even Nero. I don't recommend Nero personally.... but you can if you want.
As always, giving +Karma is always appreciated around here... same with the
PSP site. Hope I've helped, if you have any other questions then just post them in the Help Section and (hopefully) somebody can answer them for you. Welcome to the site! Enjoy!
