My work blends a few influences relevant to the platform while showcasing the machine itself along with the games the platform ran:
1) Music made using sounds available on the platform (where possible)
2) The platform's boot screen (if possible)
3) Commercial influences usually in the form of the platform's marketing jingle.
4) The platform's packaging.
In this way, the platform video itself gives an accurate interpretation of what the platform is, was marketed as, and what it looked and sounded like.
My apologies for the lack of a Youtube video. Youtube is REFUSING to process my video uploads on my account! The only audio in the clip is the game audio when the games are showing, when the box art appears, no audio plays. Why? because the platform box isn't very inspiring so I kept it simple.
