So, the copyright issues have been resolved now then, we might guess..?
Still, it seems that the original artists left years ago since the new UI has zero integration with the game graphics and perhaps even were just quickly thrown together by a developer...
But damn, if they are the original devs, they would have the source material to use the tiles to expand upon the play area. Also, they could have come to this forum and hired someone to draw a nicer control pad and buttons for them!
