Making another new thread to discuss ideas for a potential 100% category for SMB2.

Since SMB2's progression is based on levels completed, I feel that for a potential 100% category it should simply complete everything the game keeps track of in each level. Reviewing Xkeeper's disassembly this would mainly include these three things:

-Powerup Mushrooms
-1up Mushrooms
-Whether the key has been used in levels with a key and lock

Other considerations I would not include:

-Character contribution (it's a simple statistic, nothing more)
-P4 lives (for obvious reasons)
-Any collectables that respawn (cherries, stars, plants, stopwatches, etc.)
-Visiting all rooms (the game does not keep track of this)

So yeah, ultimately my proposal would combine two categories we already have and also include unlocking all doors with the key. Thoughts? Anything I may have missed?
