Dance: UK seems to have 2 version of the game, one with the mat and one standalone.
Searching for the barcode below, i only get the standalone game.
Barcode: 5060015454972
PCID: 58879
In this case, we have chosen to display only the game cover in CORE.
You are of course free to upload your own cover in your personal database.
I have updated the game in CORE and added the PCID.
Thank you for reporting.
