I hope you are doing these experiments in your own modfolder: <OFP>\
<Modfolder>\Bin\You do not
need to convert it back to bin after editing it as a cpp.
1. Install BinView by the Chain of Command:
download here2. Find your way to <OFP>\Res\Bin\ and double-click on config.bin - it should open automatically with BinView
3. From the taskbar, choose File ---> Save. It will be saved as a cpp. Move this to your <Modfolder>\Bin\
4. Edit that cpp as described by Sanctuary in
this thread. You need to add all the listed
enum { ... }; to the config.cpp
5. Run your own Mod from its modfolder
