Now you just need to seal the system in plastic just like it was on the public displays and have a controller attached to a flexible rubber thingy. Oh, and turn the sound down real low and ambient muzak up to make it feel like you are in Toys 'r Us or whatever.
I remember seeing Last Alert in a similar kiosk. It was the first time I saw a CD game EVER. All it did was sit on the title screen and play music, but I remember which parts of the music I heard. Now when I listen to my very own copy of Last Alert on my very own TG-16-CD-ROM, I let the title screen go until that part at the music so I can pretend I am 20 or 30 years younger.
