First entry of the series to be given an international release.
The game has an odd glitch that allows the player to edit maps that they are currently playing in either the Campaign or War Room modes. This allows the player to simply make the enemy immediately surrender and win.
Due to the game's original Japanese release date being scheduled during the aftermath of the 9/11 terrorist attacks in the U.S, its release was ultimately postponed and didn't launch in Japan until after the completion of the sequel where it was released as a compilation called Game Boy Wars Advance 1+2.
In the Japanese release, Nell wears a buttoned-up tank top and a short skirt. During localization for the international release, it was changed to a full shirt and a skirt that reaches the knees.
