Alright, so im kinda ****ed right now. Im playing A link to the Past on my GBA SP, after not playing for years, and i SHOULD be at part 9 (look here ) but after i died a couple times it gave me the option of starting back on the pyramid (where i last saved the game) OR starting way back in the sanctuary...my dumbass picked the sanctuary. now im stuck in the light world but i need to go back the dark world! how do i go back?

You find your way back by going to the Zelda thread and asking there.

Alternatively, there's portals in the castle and outside of the lost woods IIRC.
