The Internet Archive already has some emulation support, perhaps Android support is needed? If OP is willing to transfer the copyright to the Archive for $1, I'm happy to facilitate so it has a permanent home.
If it's being distributed by a piracy site, and the game had any sort of protection to make sure people actually bought it, then probably they're storing/offering a pre-cracked version, which certainly shouldn't (or wouldn't) be signed by anyone.
