Has anybody heard of the Famicom Contra sample? I mean this: http://www.nintendoplayer.com/proto-power/contra-famicom-sam...

If you look here: http://www.nintendoplayer.com/prototype/  Under "released famicom game prototypes", that Contra sample is listed as publicly dumped. However, it isn't linked. Anybody know where to get the ROM if it's publicly dumped?
