I want to make an osu!mania skin that looks like 9K for each number of keys, just that the unused columns would not have any notes and the unused keys wouldn't work (because they're unused obviously) (that means that barlines should act like 9K as well!). Now, I have thought of 2 ways how I could make it work, provided that those are possible: My first idea is to use different mania-stage-bottom.png for each number of keys. My second idea is to have mania-stage-bottom.png to be drawn below the keys instead of above.
Is one of those two ideas possible? If not, would there be another way to reach my desired result?
