This program makes a patch to be used with ROMPatcher. The purpose of this patch is to force the phone to use files in C: before the same file in Z:
For example, if you have
c:\resource\apps\About.r01
then it will take precedence over
z:\resource\apps\About.r01
This is useful to fake Symbian so that it takes your own file, before the original one. As files in C: are read+write, you can modify them.
Instructions:- From your phone copy the file z:\sys\bin\EFSrv.dll to the PC in the same folder where you have c2z.exe and then run c2z.exe
- It will generate the file c2z.rmp
- Now copy the generated rmp file to your mobile in E:\Patches
- Start ROMPatcher and enable the patch
Which files can be overriden?
At least *.RSC , *.MBM, *.INI, *.R??, *.TXT
Changelog 11.05.08:

Now it can replace
z:\resource\versions\sw.txt &
z:\system\data\swipolicy.ini and many others. Therefore some of the previous patches are no longer needed.

Still can not load some DLLs and EXEs but I am working on it.
On some FP1 phone models, by default the files in C: are used before the same file in Z: If your phone exihibits this behaviour then you don't need this patch. But this might not be true for all files.
