Mario Tennis was Mario's second time on the court, after Mario's Tennis on the Virtual Boy. It introduced a lot of gameplay mechanics that would carry on to future installments. Also, Waluigi.

From here, you can press the following buttons:

B: Player model viewer. The following controls are used:
A: Zoom in.

D-Pad Down: Starts animation.
D-Pad Up: Stop animation.
D-Pad Left/Right: Cycle through the animation frames.
L/R: Switch characters.
Start: Change background color.
Start: Object model viewer. Basically the same deal as above, but for objects rather than players.
C-Left: "no controller" screen.
C-Up: "congratulations" screen.
C-Down: Intro cutscene.
C-Right: Kicks you to the "TENNIS MENU," which allows you to choose which mode and how many characters you want to play with.
D-Pad Down: Starts a quarterfinals match in the Mushroom Cup, with two green Yoshis controlled by Player 1. Strangely, the bracket shown in the pause menu shows no characters.
It's Mario Tennis. No specific kind, just Mario Tennis.
The Japanese version uses a different logo. Also, Mario and Luigi say "Mario Tennis 64!" in the Japanese version, while in other versions, they say "Mario Tennis!", followed by Mario alone saying "Hoohoo!" like in Mario Golf. As usual, "Push Start" was changed to "Press Start".
The Ring Tournament mode is not available by default in the European version. However, it can be re-enabled with a button code: hold L + R and select Special Games and the Ring Tournament mode will appear. Unfortunately, the codes from the Japanese and US versions do not work on the European version, and it is unclear if there are any codes compatible with the European version.

The Code Entry screen is called as such in the US version, whereas the Japanese version calls it Entry Code instead.
The Ring Tournament mode was removed from the Wii Virtual Console release due to the online leaderboard being shut down. Its icon is still there, but it is skipped over in the menu. It was implemented again in the Wii U VC release. Additionally, Alex, Nina, Harry, and Kate are no longer playable in the Virtual Console and Nintendo Switch Online versions of the game. The Super Mario, Peach, Yoshi, Wario, Waluigi, and Bowser Courts cannot be unlocked either. This is due to the game needing to be connected to the Game Boy Color version of Mario Tennis to unlock this content, which the Wii, Wii U, and Switch obviously cannot do. Despite this, the data for all the characters and courts are still in the game.
