How to do low level kitchen modifications?

[atomclock]

I was wondering if someone would share some information about low level modification of the rom kitchens. I have been working with Dog Guys kitchen and an original rom image and i have done some extensive modifications. Unfortunately, it is really just a cluged mess. The problem is that I don't know how to modify the underlying registry keys.

NOTE: I am not talking about *.rgu files in OEM packages and I am not talking about boot.rgu.

I am talking about the registry keys associated with the version of the compact framework built into the rom. Or the registry entries that define what applications are initially set on the program menu. Or the keys with the various application that are installed in the rom by default.

I have done a great deal of searching and I clearly don't know what the key words are to find this information. It must exist because both DCD and No2chem were able to either find it or derive it. I am just hoping someone will point me in a direction where I might be able to learn the next stage of rom customization beyond simply adding different OEM packages.

Thanks

most of the programs have their own folders. In each folder there is .rgu file. that file contains registery entries for that program.

in oem folder there are folders oemapps and operator. those folders contain more than one programs in one folder. all the registry entries that are related to all those programs are in one single rgu file in those folder. There are some registry entries in .provxml files as well.
when one file contains registry entries for more than one program, most of the entries that belong to a single program will be next to each other ( not always true )

Could you tell me where the registry information is for the contents of the SYS directory. for example where are the registry entries for SYS/NET. there isn't a corresponding .rgu file.

thanks.

sys folder has lots of other subfolders .. they have their rgu files.
There are some programs in bin format. they are already encoded i think.
You can put registry entries in a cab and put it in extened rom .. and run it after hardreset .. that way it will overwrite the original keys.

atomclock, I found this old thread concerning a solution and troubles with cooking .net CF 3.5 into a ROM:

Thats funny... That is the oem package I'm using in my rom.

There seems to be three possible avenues to work this issue.
1. Build oem's and hope that the registry keys in the oem's .rgu file COMPLETELY overwrite the original entries. (Oemizer is a good tool for this http://tiermann.net/index.php?option=com_content&view=article&id=3:personal-oemizer&catid=1:Desktop&Itemid=3 )
2. Review the registry after a rom is written and create an xml file that will overwrite and delete all unnecessary registry keys (here is a link for anyone interested http://forum.xda-developers.com/showthread.php?t=366337&highlight=kitchen )

3. Get the inside information as to where the registry keys are actually located and make changes at the source instead of trying to patch it after the fact. (If someone has a link for this information please provide)

Why is it so impossible to get the necessary information to proceed with option 3.

I want to port the drivers from the current official rom to an old wm5 kitchen. I really need to get access to the underlying workings.

NOTE: I already know how to proceed with options 1 and 2. I need the information for number 3.

If you can answer the following question then you have the information I want.

Where are the registry entries for the BUILT IN .net framework (/SYS/NET)?

Thanks
