Here we have a Platinum copy of “Dancing Stage Party Edition”, bundled with a dance mat from Logic3. A sticker on the cardboard box declares: “Dancing Stage Party Edition included with this product”.
I had never seen this game + dance mat combination before.
Here we have a sealed copy of a quite rare controller pack from Konami.
The bundle contains the English version of the game “Dancing Stage EuroMix” and a Konami dance mat.
I know that there also are French and Italian variants of this pack and I suspect there is a German version as well.
