-- SCGB_GAMEFREAK_LOGO before calling Copyright, so the card runs on
-- PREDEFPAL_GAMEFREAK_LOGO_BG rather than the default BGP Gold's DMG boot
-- leaves up (../pokecrystal/engine/movie/splash.asm:21-30).  The card used to
-- hardcode a white fill and Crystal shipped no extracted splash at all, so the
-- first screen of the game was blank white.
