Hi,
I write this for information purpose : there is an extremely rare Not for sale demo from Sega headquarters to add to the missing games list. It contains songs that had to be purchased online. It has never been listed anywhere.
Serial is T-00000M.
Best regards
Yeah, I've seen one on eBay in November, sadly, it was being sold by a known scammer. It's a known title, probably forgotten to be added into the missing list, thanks.
