I have edited the Y 1.5 patch (~32MB) by adding the a/0/0/7 GARC (~ 1.08GB) and the resulting romfs is somehow 2GB? I'm pretty sure it's a RomFs Builder issue. Any ideas how to downsize it?

strange.
a007 is 3d model, right ?

try to rebuild you romfs

Yes, it is indeed the models. I tried twice already, always the same size (2.13 GB). I just finished installing the hack so I know it works, therefore, nothing is broken.

I see the rebuilding process needs a correct .rsf file, any advice about how I can generate one?

I need it for the monster hunter 4 ultimate 1.1 update.

I don't know, try to edit the SerialCode, TitleID, and all other MH4 Update stuff.
You can also open the DecryptedExHeader with CtrTool for see a lot of infos.

Oh i didn't know that, do you know which option displays that info? I tried ctrtool -i DecryptedExHeader.bin but it says "unknown file"

Just specify the file format, like so:

Code:
ctrtool -t exheader -i DecryptedExHeader.bin

Thanks, that gave me the needed info

Now I'm on the last step and there is an error with the makerom, the one from the pack of the OP says that it is not a valid windows application.

I downloaded a 1.1 version of the makerom from somewhere else, but after the instruction in the batch file, the cxi never builds and the makerom just continues for a long time with no result

You need also to edit the batch file with the minor/major version and other stuff.
But I don't know more about other patch rebuilding, sorry
