My take on a versus/co-op mode with classic levels mostly by editing libsmashhit.so. Only works with ARM64 devices. Inspired by Knot126's take:

Scoring sounds doesn't play in zen and versus modes, menu fog in non-classic modes in low quality displays correctly (fixed a vanilla bug, here's how to do it in your mod: User:Ham numbers/How to fix fog color in other game modes in low quality), and ranks in co-op are changed:
0..1999: beginners
2000..3999: conflicted
4000..5999: cooperative
6000..7999: connected
8000..9999: syncronized
10000..11999: symbiotic
12000..13999: telepathic
14000..∞: mediocre (same as classic/training/mayhem)
