Question about headers

You can use LeetSketcher's Headerizer to add or remove header requirements from any patch you have.

BPS patches are trickier, because FLIPS checks if the ROM is the correct hash before it applies the patch.  If you're using more than one BPS patch, you'll have to apply one BPS patch to a clean ROM, use LunarIPS to make an IPS patch from the changes (to bypass the hash check), and then apply THAT to your cumulative ROM.
