Mooncat has an earlier version of the game's icon within "sIconMonoUnused". This sprite contains the earliest set of Library icons, but only in the dark, uncolored palette used when a game hasn't been dusted off yet.
The only difference, ignoring that these are using two different palettes, is that it used to be flipped horizontally.
Unused Sounds#

A very subtly different version of the mushroom bounce sound (the waveform is stretched out, but it fades out sooner).
UFO 50's sounds usually do not belong to any particular game, but this can be identified as a Mooncat sound because its code attempts to mute this sound effect when ground pounding enemies. This may be an oversight, if the sound was switched out during development.
