Hey :) So there's a glitch you can do on stages 4 and 6 to skip the songs by ejecting the disc when you hit the battle phase. I think you could probably eject it on other songs when it says "end" on the bottom right, to save more time. I'm wondering if this would be allowed, as it requires messing with hardware, also I'm thinking it may make the game perform worse to do it, but not sure on that.
Seems like a different kind of run/category to me if you are totally skipping songs versus skipping portions of songs.
Rule has changed to account for opening the disc tray when END appears for each song.
"Time starts on selecting Level 1.
Time ends on the thunder strike after beating Zowie OR when U-1's pose appears on screen after opening the disc tray.
Opening the disc tray to skip songs is allowed."
