I tested it on a clean Emerald rom, went to all the offsets you listed and entered them. I then copied FD0200E7E9E6EADDEAD9D800E8DCD900E4E3DDE7E3E2DDE2DBADFECEDCD900E4E3DDE7E3E200DAD5D8D9D800D5EBD5EDABFB to like 9CB090 and then at that offset it says to put the pointer I tried both 91 B0 9C 08 and 90 B0 9C 08 and still nothing. What it shows is the game going black followed by what appears to be the textbox graphic in the top left corner. Weird.
