Anti-Piracy Check
Before any stage is loaded, the game runs a checksum routine on RAM 37FB to 3801, which normally stores the "NINTENDO" part of the title screen's copyright graphic. If the checksum doesn't match, the game will be altered in the following ways:
- The first Snapjaw will turn orange.
- The topmost Snapjaw's Y position will go crazy until he eventually lands on the third platform in the water.
- Blue Snapjaws will start falling through floors.
- Any time Donkey Kong Jr. jumps, the game acts as if he jumped over an enemy.
- Most importantly, Jr. won't be able to climb vines, making the game impossible to play.
Unused Graphics
This lightbulb is located with the fruit graphics. It was probably intended to be used in Mario's Hideout, but the standard fruits are used instead.
These graphics are leftovers from Donkey Kong, and have no use in this game.
These tiles are in the ROM just in case Nintendo wanted to use their full name, Nintendo Co., Ltd.
Version Differences

The two "main" versions of the game have different title screens. The earlier version (also the only one released in America) does not abbreviate the title and uses a different title screen palette.

Donkey Kong Jr. expands the number of characters in the high score screen from 3 to 12. The default high scores were increased, as well.
Level Order
All versions of the game besides the US F-2 set have a consistent level order. The US F-2 set matches the first three levels of the US version of the original Donkey Kong game: 1-4, 1-2-4, and 1-3-4.
