You're still hyping over this?
You should honestly give up. He did the same thing for Brawl Masquerade. Showing previews, but never releasing anything and hyping people up, but never delivering.
You're better off making a request thread for someone to make their own script.
But who knows? By some random "miracle", he could come back with a release. Though right now, you're wasting your breath.
I would really like to be proved wrong, but I have lost hope. Maybe he'll reveal more when the next version of P:M is out.
All he has to do is upload his fix of BrawlBox somewhere. Which should be 5 minutes of work.
