ATP Tour Championship Tennis
Also known as: ATP Tour (EU) Developer: SIMS Publisher: Sega Platform: Genesis Released in US: 1994 Released in EU: 1994 This game has a hidden developer message. This game has debugging material.

This page is rather stubbly and could use some expansion. Are you a bad enough dude to rescue this article?

ATP Tour Championship Tennis is a sequel to Wimbledon Championship Tennis... sort of.

Debugging Facilities

Enter the code B A C A C A B A on the Sega screen. A chime will confirm if you did it correctly. You can re-enter this code multiple times; it raises a counter (stored in byte $FFF18E). This is important, as some of the debugging facilities won't be accessible unless you repeat the code enough times.

Debug Menu

After entering the code once, a new DEBUG entry will appear at the bottom of the Options menu.

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: Is the music heard in the debug menu used anywhere? Figure out what the Effect in Court Locations is really for. What exactly are the stats in the Data Window? What does Player Face do? Other debugging functions?

To do: EU ROM There are likely more debugging features hidden, but I stupidly accidentally chose not to save the IDB file all those years ago and was too angry to go back.

COURT LOCATIONS

Choosing this option will take you to the tennis court, where you control the camera. Hold A and press Up and Down to change which court you view. Hold C and press Up and Down to change the Effect number, which seems to affect audience reactions? Press Start to go back to the debug menu.

PLAYER ANIMATIONS

This screen lets you check player animations. A description of the screen's controls are on screen (the A button controls are on the top).

DATA WINDOW

This is an option that shows some data on screen in-game. If set to DATA, various stats will appear at the top and bottom of the screen.

If set to HISTORY, alternate stats will appear instead.

SCORE SETUP

This switch sets the initial score to 40-0 you if set to WINNING or 0-40 opponent if set to LOSING. Either setting will also start off on Set 1 Game 6.

PLAYER FACE

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: What does this do?

DATA EDITOR

If you entered the debug code three times or more, a Data Editor entry will appear at the end of the debug menu. In this menu, you can change the various numeric stats for any of the save files in the game.

Miscellaneous Debugging Functionality

These are also all enabled by just entering the code once.

In-game, press Start to enter a Replay mode where using Up and Down will step through what just happened prior to hitting Start incrementally.

To do: Does the History data have anything to do with this thing?

Hidden Text

Located at 0x15B52 in the US ROM (0x15BDA for Europe) is the following string:

FUCKSEGA

This string is written to RAM at the start of the game (0xFF53F2) and to SRAM when the save data is first initialized. After booting, the game checks player slots 1-4 to see if the string "FUCKSEGA" is present, comparing it with the string in RAM character-by-character. If any one of the slots fails the test, the player data in that slot is reset.
