To get the 3 hidden courts do the following. You have to use the run command in windows and this is a command line cheat just like the mini players and the alley oops. After the NBA2000.exe put (-floor gym) without the parenthesis. That will allow you to play on the gym court. You can also access the High Voltage parking lot court and the outside practice court with the -floor command. Simply put (-floor hvs) or (-floor outside) to get them. So basically there are 3 courts that you can access by using the -floor command line option. There is also a construct court and a software court but they're missing files so they won't work.
