Because it's not released by the scene. It doesn't exist.

That's a phenomena that we have for more than a year now.

This is a priviate leak someone made and gave to P2P without any connection to the scene. If there's not a single scene group interested in repacking it - and it seems that really nobody cares about this Rom - then this game is lost forever. Some kids may have it from P2P, but it's not in the archives of the scene. Just at the Micro SD card of some pirates.
