[Question] Tricking CIA to act like another title?

I have an edited Mario Kart 7 CIA that I would like to use. I want to make the 3DS think that the CIA is a copy of Pokémon Alpha Sapphire. I tried replacing the TitleID in the ExHeader, but all it gave me was a blank CIA that shows an error when trying to run it. Anyone know how I can do this?

I'm running rxTools on a 2DS with 9.2.
