I suppose the roms won't be different, but they're worth checking just in case they added a special feature or promo screen or something for a company or comp.

Anyway, I just found this resource about 69 promotional G&Ws and how many times each specific game was used for promotion:
https://www.gameandwatch.ch/en/faq-questions-answers/promo-advertising-game-watch.html

That infomation and the cases (even if just different faces) is something I didn't know and is historical/important for preserving.


Would you agree on:
1. The info on the promotional uses of each G&W game in the driver (small descriptive details too); and,
2. The art/face of each one so that users can select them. (I know the rom isn't different, but it allows a user to see the history promotional face/version of the G&W.)
