Ending Graphics

Almost ready to release a rather extensive hack project, but there is one edit left to do.

I've replaced Shadow with another character. I'm OK with the "apple" graphic that appears during Shadow's ending, but I'd like to get rid of the two throwing stars. This could easily be done by making the two star graphics transparent, but I don't know where they're located in the ROM. Can anybody tell me? Failing that, any other ideas on how to make them not appear?

Thanks!
