Does anyone know where I can find in depth information on editing hex files for BW/B2W2? I need to know how many bytes long a header is for specific parts, which bytes correspond to each bit of information and such. For example, if I open the narc file containing the trainer sprites then I would like to generate a program that can read all the hex information and process the correct parts to generate individual sprites. Yes I know tools like this exist but I want to be able to develop them and make them available for Linux platforms
