drparse creates a patch to a ppc2003 rom, to enable a new XipRegion to override files in an old XipRegion.
usage
drparse origrom newxipblock
drparse calls dumprom.exe to analyse the rom images, finds which filenames occur in both roms,
finds where in the orig rom the file information is, and creates a patch to the origrom, to redirect the original fileentries to the new rom.
the patch is in the form of '-dd' options to be processed by splitrom
