i have succesfully ripped
xbla unplugged and crackdown using wxripper and i can open them up using wx360 yet. i have no idea of how to burn to dvd+r dl
i have read textbooks guide and it says to use 360 ss merger and add the ss pfi and dmi files and merge to a .dvd file
where do i find these files please help

im using a pioneer 112 and have a 108 if it makes a differance

AS a newcomer, I suggest you first carefully read the rules, you cannot request where to find these files.
Plse take the time to explore the pinned section at the top of the Backup forum ( Backup Faq - Everything* You Need To Know PLEASE READ BEFORE ASKING QUESTIONS! ) and you will find info on the wxripper method and others.
They will also tell you how to extract your SS.bin, DMI, PFI using your X360 drive that must be connected to your PC.
I am assuming you have a hitachi (which model) if you do this, SO the DMI and PFI are not really used at this point, up to you if you want to include them.

ok sorry i didnt know about the rules i was just asking how to get them (from dvd) ill look through the link now.
yes its and hitachi 0078 with Maximus Xtreme firmware

The firmware that is flashed on a v78 is v1.6 (the v2.3 without f900 core) and it does not yet support ss.bin extraction and game partition extraction. When and if there is a firmware that can support at least do ss.bin extraction then you could complement that with the wxripper method and build a complete image. At this point, not much value wasting time on wxripper, without a ss.bin

IN the short term if you really want to backup your games, the only option I see since you have a v78 is to acquire a pc drive like the sh-D162c. That way you can do all the work in your pc without even needing to come close to your X360 Drive. ANyway you will get tired of opening your x360 .
