Trivia
Graphics
When you play NTSC cartridges on a PAL TVs that supports the mode, some colours can appear wrong. In this case the court appears blue rather than green - almost as if the game has automatically modernized from grass to hard-court surface (obviously the ball still behaves as if skimming off grass though).
Activision patch
Players who won one set against the computer could send in a photo of their TV screen and get an Activision Tennis patch.
