Sorry for the double post.
This is going to sound weird but are you sure it was a basketball game? Since I couldn't find anything else resembling the game you're describing, I thought I'd search through all the emulated arcade sports games from that period.
I found this game called Heavy Smash (1993), which is a
handball sports game, but it closely resembles what you're describing. The final match is on a space station I believe. Also a curious thing is that the European version of the game has the Korean team replaced by a Spanish team (actually, it's just the flag, the characters are the same) while the Asian and Japanese versions have a Korean team.
