Edit: btw, if anyone cares, I've added the region-free manuals patch to the custom loader module, so those should work now.
Actually, I'd still like to know how you came up with the values for updating in the future regardless after getting the data locations, offsets, and signatures from decrypted firmware.
I talk about this on the previous page.
svcBackdoor and unitinfo patches aren't in the script, but the offsets for those haven't really changed at all since older firms, and that is still true for 11.8 and 11.12 (maybe that will change if Nintendo comes up with more firms in the future, idk.)
It's also possible to extract each firm section in GM9 from a decrypted firm dump, and compare unknown firms with known firms to find the new offsets, if any, but that's only useful if a patch doesn't work and you want to double check that you have the right offsets.
keydata for N3DS is in section 2, you can check the offset in firm.c for a known firm in a hex editor, and see at which offset you can find the same data in an unknown firm (hex search helps here.)
Someone who's more knowledgeable and who cared enough could make it so the code would search for offsets on its own, instead of using hardcoded offsets, so that newer firms would just be supported by default, but that wouldn't be worth anyone's time. Nintendo probably isn't going to be coming up with too many newer firms past 11.12, and the demand for CakesFW isn't high enough. One thing that would be cool to add though is to make the code dump the firmwares from ctrnand so it would all be done automatically without having to download firms and cetks, which would be especially useful in the future if the update servers were to go down, but I don't really feel like bothering with that right now.
I'll be keeping an eye on this anyway, so if Nintendo does comes up with new firms, you don't really have to worry about doing it yourself.
