When Miyamoto was describing the room Mario and Luigi would run around in during early Super Mario 64 development, he mentioned that it was a room made of simple lego-like blocks. Since we have development files for Super Mario 64, thanks to the gigaleak, do you think he was referring to this room?

Or did he mean checkerboard patterns, like in the Shoshinkai 1995 footage?

Because that was also in the leak, except it's green instead of red for some reason.
