It is a homebrew that poped up a few years ago on ebay (and sold for tons of money). Vektorlogiks got a ton of them in, they were modified Puzzle D Pon carts, and shared the same music. The game plays ok, but it is unfinished, and basicly you can't get passed level 7 (there are not enough crystals to complete the board). It is for the collector only, and even that is a stretch, as for $200 it is still a crappy, unofficial, homebrew hacked game that is not even finished.
