drparse creates a patch to a ppc2003 rom, to enable a new XipRegion to override files in an old XipRegion.
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|
