Usable Magic for all Characters

can you make a patch for a headered rom?

seeing as how most patches use headered roms, this might conflict with many other patches

Well it won'T conflict with other patches but with the game itself if it's apply to a headered ROM, but worst thing the person who wants to apply this patch can remove the header, apply the patch and put a new header after. How many people work with headered ROM? I thought many people were finding headers a pain because you always have to calculate +200 bytes whatever you do. I always keep the header but in the end it's a personal preference.
