Super Nu Series

It seems like you’re referring to a series of abbreviations: SNU-U, SNU-O, SNU-V, SNU-SM, SFU, SFO, and SSM. However, without further context, it’s difficult to determine what these abbreviations represent. They could potentially be related to a specific product line, game titles, software versions, or some other categorization.

If you could provide more information about the context in which these abbreviations are used, such as the industry or field they belong to, I’d be better equipped to assist you in understanding what they refer to.
