i dont know much about PS2 but i know quite a bit about xbox stuff

well to backup a xbox game to a dvd so it works in your xbox u need to either modchip your xbox or "softmod" your xbox... once u do this u can use your xbox's dvd-rom drive to read the game data and then use a program (that runs on the xbox) called "dvd2xbox" to copy the game into the xbox's hard drive then u FTP into the xbox from your PC with a program called QUIX (theres other programs out there but this is the way i do it) then u can use QUIX to transfer the game data into your PC... it will be stored in ISO format... then u just use a basic program like NERO and burn it to a DVD and thats that

if u dont want to get a modchip... softmoding will work... if u dont want to open up your xbox case to softmod then u will need a way to transfer the exploited saved game files onto a xbox memory card and u need a game like 007 or original splinter cell etc in order to install softmod etc etc etc.... but what i did was open up the xbox case and connect the xbox's hard drive into the pc's IDE cable and transfer over the exploit that way ... opening xbox case is simple... all u need is a TORX 20 screw driver and once the case is off the rest u can do without removing ANYTHING ... u will just need to disconnect a cable or two which is pretty simple etc etc etc.... basically the program u will need is "XBoxHDM" (xbox hard drive manager) and "Kingroach's" softmod exploit program that works with XBoxHDM... then u burn it to a cd and u use that cd (which runs on your pc) to communicate with the xbox's hard drive once u got it connected to the PC's ide cable etc.

thats the basic idea of it... but theres a little more to it than what i said ... but what i said is pretty much what u need to do.

have a good day
