Easy Way to Get Points
To get a lot of points be Gotenks after you unlock him and with the points that are already saved up buy stuff for mode and settings. Go to bonus settings and you will see free supers and instant death. Put them both on. Use Gotenks' special by pressing the control pad down, down, left, right, and L. It should kill your enemy in one shot. Do this and you will get 25,000 points every time you beat tournament mode.
