I'm a bit of a newb, but:
It looks like the company listed as "property of ____ocom" refers to "property of "Eurocom""
There are 3 carts it could be based on years of release.
1. it could be a very early prototype for 40winks.
2. it could be an early duke nukem zero hour
or 3. NBA Showtime: NBA on NBC
Its also possible that 4. it could be something else entirely. But I'm sure that you've already considered those ideas. an idea I had was also mortal kombat 4, but I can't find the release date of the n64 version, if it was different than arcades.
