LC-3 Assembly Code for Undo Feature Key Points:

Save State Before Move: Every time the user makes a move, the current board state is saved in TEMP_STORAGE.

Undo Move: If the user presses 'u', the last saved board state is restored from TEMP_STORAGE back into BOARD_ADDRESS.

This code provides the basic structure to implement an undo feature in your LC-3 version of 2048. The code assumes that you have other parts of the game (like board rendering and movement logic) already implemented. You can expand on this by adding other gameplay features as needed.
