How to Customize a Custom Rom: Adding/Removing Programs

[tstack77]

I am trying to modify whosdaman's diamond ROM (v1.6 full) but can't get past the "PrepIt" stage with the vogue kitchen tools.

cmd.exe output:

Processing Input.nbh
Cleaning up prior runs....
The system cannot find the file specified.

Extracting the OS from the ROM...
C:\Vogue_Kitchen_tools\Temp\extract\02_OS.nb
.... Done.
1 file(s) copied.

In dumprom.exe I get an endless stream of this:

Error: could not find pointer for ofs 69685431
Error: could not find pointer for ofs 69685432
Error: could not find pointer for ofs 69685433
Error: could not find pointer for ofs 69685434
...(repeated indefinitely)

If I close out the dumprom window I'm prompted to terminate the batch job, if I select no it moves on to the other steps and everything seems fine. However, the modified ROM stalls on first boot when loading the OS after flashing.

This is the first and only ROM that I have had any issues with...is there something I am doing wrong or can somebody else replicate/solve this?
