Ummm didn't you try to inject the mario rom hack with super mario cia?
It was really not too hard.

Use that program, is from a post on wololo.net website about snes rom injections, you already know how to decrypt cia roms and extract them yes? Use that program to inject the rom hack, make sure they work in a emulator first like SNES9X.
Upon loading the rom, look at the display for the rom infomation (Or click file and rom information) after loading the rom and see if it says "High Or LOW" rom and the file size in megabits, then use the program to select the DATA.BIN file (injected SNES rom) and select the rom for injection. (You must manually select the file size of the rom. is also included in the rom info when the emulator loads it)
Then rebuild the cia and install it, is how i did it. It works and i have proof.
I did that with super mario world, Brutal mario is 4MB so is 32mb you would select from the options before injection. But you have to make sure the rom works in a emulator first.
