Portal at the end of the cult of lavos area, and the start of the 1999 area has the circles misaligned (there's a crescent moon of black, that doesn't have the portal effect).
No music on the worldmap of 1999.
*edit- Just watched the "movie." Good Job. I was laughing through a good chunk of that. "Frog: next time I pick the movie." lol.
*edit2- and now I AM getting music on the 1999 worldmap... weird.
*edit3- OK, so it's using track 15 for the worldmap in 1999, which is a non-looping track. So one the rather short song plays once, it's just silence afterwards until something causes the music to change or restart. Not sure how the SPC sounds, as I'm using MSU audio.
Nope, silence happens on SPC as well.
*edit4- question, is it possible to open the sealed chest in the residence right below the sewer access in 1999?
Also, In 1999 Proto Dome, there should be some extra text somewhere if Robo is in the party.
