I realize this is old but maybe it'll still help...I have GC GBE and with that rom if you goto system/media/ there is a file called bootanimation.zip. That is the file that needs replacing for a new boot animation (go figure). However the zip that this site creates doesn't have a bootanimation.zip it has a sanim.zip (have no idea what that is about) but anyway I just pulled that file from the zip renamed it to bootanimation and moved it over to my system/media folder after deleting the original....correction I backed up the original file then deleted it and replaced with the new one.
