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.
