I just revisited this video and this is the pinned comment (3 months ago)):
From The Lost Media Wiki
"Minor Update - I actually got in touch with the John Slack who I sent a message to and he confirmed he was the Media Design guy! However he has no materials relating to the games and doesn't know where to go to find them. It looks like this may come down to old Burger King locations or employees having held onto this stuff."
Also recent comments so far dont have any extra leads
