US Looking for Megaman Builds

Any leads on who may have these are also wanted.
Debug, Preview, Beta, Alpha, E3 etc
Megaman or Rockman apply.

Cancelled games (most wanted)
-Megaman Legends 3 (Supposedly carts were made but then never made it to a trade show due to earthquake disaster)
-Megaman Universe (Was on partnernet and available at some point - also looking for leads on owners because of this)
-Maverick Hunter (FPS game pitch. There's one owner I know of but I can't find them outside of the videos they uploaded)

X games
-X8 prototypes
-X7 prototypes
-X5 prototypes
-X4 Prototypes
-Command Mission prototypes

Legends games
-Megaman Legends E3 1997 (AKA Rockman NEO - the one where Megaman explodes upon losing all his life)
-Megaman Legends 1 prototypes
-Megaman Legends 2 prototypes
-Misadventures of Tron Bonne prototypes
-Megaman 64 prototypes (there should be 1 more cart around but this is least desirable)
