Bart Simpson vs. the entire camp.

To do: Nintendo Power #29 covered a version of this game with plenty of differences (Mostly graphical).

Hidden Areas

I Love Maria

At the internal end of the first level are sections reading several messages, starting with "I LOVE MARIA". They can be accessed by warping to them with the A + Start debug key.

When advancing, another message reads:

I PROMISE TO LIVE
WITH YOU AND TO BE
FAITHFUL TO YOU FOR
THE REST OF OUR
LIVES

Walking further (or skipping to the next section) reveals more text:

I PROMISE TO
SUPPORT AND
ENCOURAGE YOU IN
THE PURSUIT OF YOUR
GOALS AND I PROMISE
TO MAKE A LOVING
HOME WITH YOU

The level ends wth the message:

MARK AND MARIA SAW
  THE WORLD
  JUNE  1990

Debug Material

Debug Mode

While the game is paused, press Right, Up, B, A, Left, A, Down, B, A, Right, Down (RUB A LAD BARD). Pressing Up and Down changes the option selected, indicated by the number on the top-left corner. "07 31 91" is the compilation date.

Pressing A will cause the following effects, if the option selected is one of the values seen below:

• 0 - Toggle Infinite Health, gain an extra life (note that Bart will still die when falling into a pit).
• 1 - 80 Lives, 25 Boomerangs, and more HP.
• 2 - Increase HP by 1.

Pressing Start goes back to the game with the options selected. Pressing B goes to the level selected (unless no data is associated, then it does nothing).

Full Debug Mode

To do: Add more details on the Full Debug Mode, especially documenting the meaning of the unknown values.

The results of debug keys A + Select.

The results of debug keys B + Select.

The very end and leftover section of Level 1.

While the game is paused, press Right, Up, B, Select, A, Left, A, Down, B, A, Right, Down (RUB SALAD BARD). Seems it was some kind of obfuscation to the code, to prevent those who look for cheats inside the ROM from finding something actually interesting.

It offers the following additional features:

• 3 - Displays a counter of camp staff opponents on the screen to the left of the health points.
• 4 - Enables specific key combinations to toggle debug behavior.
  • A + Start: Advances to the next section in the current level. This also includes sections normally inaccessible, like the "I LOVE MARIA" section at the end of level 1. At the very end of each level are often leftover sections.
  • B + Start: Seems to restart the current section.
  • A + Select: Probably a graphics test. Displays background tiles on the level background in ascending order.
  • B + Select: Another graphics test, this time displaying foreground tiles on the level background in ascending order.
• 5 - Makes Bart run faster.
• 6 - Seems to display spawn locations of opponents in the level as black tiles, which mostly appear on the ground, thus making characters fall through them.
• 7 - Displays 4 hexadecimal numbers in the second line of the status bar with unknown meaning.
• 8 - Displays a hexadecimal number above the "LI" letters of the "LIVES" display with unknown meaning.
• 9 - Displays 3 hexadecimal numbers in the second line of the status bar.
  • The first number displays the number of active objects on screen.
  • The second number changes when the level screen scrolls.
  • The third number identifies the current sprite or animation of Bart.
• A - Displays 2 hexadecimal numbers in the second line of the status bar, showing the X and Y coordinate of the visible level area.
• B - Displays a counter to the left of the boomerang counter with unknown meaning.
• C/D/E/F - Scrolls the level screen into the directions left, right, up or down by 5 tiles.
• G - Unclear what this does.
• H - Unclear what this does.
• I - Displays a hexadecimal number to the left of the boomerang counter (prefixed with an O character) with unknown meaning.
• J - Kills the player and costs 1 life.
