Ecco 2 Prototype Cartridge: Anyone found it?

[Epicenter]

Hello, I'm Epicenter. I run the Ecco 2 Beta Web Site (http://ecco2beta.2ya.com). I was wondering if anyone had managed to find a copy of the Ecco 2 (the tides of time) pre-release prototype cartridge. Perhaps pirated, or a demo cartridge, anything like that, would be greatly appreciated, and benefit greatly to the site! :) I'd be willing to pay for it, or trade for some rare, unlicensed NES carts, if anyone wants these things. :)

Thanks!
