[NES] Stadium Events wrong system identifier

[robotriot]

Just a minor mistake: the "Non-U.S." version of Stadium Events has "NES" as the system, while all the other NES games have "Nintendo NES".

Ugh.

I'll fix it on my end, I'll need the section editor with the source data to correct it as well, please confirm.
