First, Accession Releases are self booting *.CDI's
The IP.BIN is hidden from you after buring, because it is in the BootStrap of the CD, which is out side of the browsable file system.
So you shouldnt have to patch it for self booting, but if you still need the IP.BIN, you need CDIRip and ISOFix, both can be found

1) Use cdirip to cut the ".cdi"image to ".iso" image.
2) isofix TData02.iso New.ISO 11700
after that,you will have a file called "bootfile" which is really your ip.bin so rename it that.
