I thought long and hard about the various reasons why certain games dont work on USB advance.I did a lot of hex poking around and I figured out (e.g. crash n burn)that the SLUS* file checks for the DNAS300.IMG right after loading the boot screen,And that's where it hung so i examined the iopr*.IMG from dbz budokai 3 and i noticed that the files where very similar and perhaps the only difference between the 2 is that the DNAS file had some form of cd-check routine in it.So i regenerated the disc but renaming the IOPR*.IMG from dbz to the DNAS300.IMG ON the crash n burn disc .Loaded it up in USB advance and BINGO,it loaded up 100%

*****************3.0 Chapter 1 -Disc-overy!****************

-First of all lets open up the disc in windows explorer.
-Search somewhere on the disc for "DNAS*.IMG"
-If this is a DNAS game it will find a DNAS file,make note of the file name e.g."DNAS280.IMG"
-Now open up the Ps2 DVD game in windows explorer etc and press cntr+a to select all the files and folders here,now copy all the files to a folder on your hard drive.Can be any folder just remember where you put them obviously:)

*****************4.0 chapter 2 - DNAS?no thank you!*****************

-Now here's where you need some original ps2 games,search each disk for some files called "IOPR*.IMG".Look for one that corresponds to the file name above eg. juiced from memory is DNAS280.IMG,I got my corresponding IOPR file from Sonys own Demo disc(thanx sony:).So select the corresponding IOPR280.IMG file (NOTE you must take the corresponding IOPR that matches the DNAS file name e.g.IOPR280.IMG for DNAS280.IMG or it wont work) and copy it into the folder on your hard drive where you copied the contents of the disc as done above.Delete the old DNAS file in here and rename this IOPR file to what the DNAS file was called eg DNAS280.IMG.
-Don't worry if file sizes don't match:)
