WTB: Ganbare Goemon 2 Sample/Prototype

[Bramsworth]

Hello,

I saw a prototype of this game sold on Yahoo Japan auctions some time ago. I have a faint memory of seeing some English blog or maybe forum post mentioning it among other things from the same seller of the auction. Whether they bought it or not, I don't know. So this post is basically to see if anyone here may have obtained it. I'm a big Goemon fan so this would be neat to have.

Thanks!
