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.

In this game, there's actually an ending if you beat all of the courses in the last plane. The only thing is, to get the ending, the game has to consider the courses as being beaten, which doesn't happen until you get to the ranking screen of that specific course. I'm wondering if I should require the all courses and last plane categories to get the ending. Additionally, There is a screen with a password for the next plane at the end of the other planes, and those could be considered as "endings", and those are achieved under the same conditions, so maybe those should be required too. What do y'all think?

There are actually 4 planes in this game. You get a password after beating all the courses in 1 section, which allows you to open the next plane, which has completely new levels. This makes a total of 16 courses, not 4, and 100 tracks. I believe that the all courses category should be all courses in all the planes, given this. The all courses category could be renamed first plane.
