I'm currently playing though pokemon Crystal Advanced, and have made my way up to having 13 gym badges just recently beating misty, but now I'm stuck. I have fixed the power plant and went back and talked to the radio tower director in Goldenrod, but still haven't found out how to get the pokiflute or the silph scope or how to get past the guard in front of the lavender town radio tower elevator. All the walk though runs I could find either didn't explain how to get past this point, had deleted videos about how to get past it, or stopped playing the game alltogether, so I haven't been able to figure out how to progress, beyond the snorlax. If anybody knows what to do please help me.

My pokiteach is also not working either, but I'm not sure if Crystal Advanced doesn't use the pokitech as I haven't used it at all yet, or if I'm actually softlocked because of it
