Debug Monitor

To do: More parameters and menus.

From left to right, the headings are アドレス (Address), コマンド (Command), and データ (Data). トーン means "tone".

Easter Eggs

Programmer's Daughter

Enter the Japanese word おおくほななこ (Ookubo Nanako) as Player 1's name. A young girl will appear and give a speech:

Japanese	English
わたし、 おおくぼななこ！ ２がつ１１にちの ケンコクキネンビ うまれ！ おぼえやすいでしょ ウフ！ パパのつくったゲーム ヨロシクね！	I'm Nanako Ookubo! I was born on Feb. 11th, the day Japan was founded. That's easy to remember, isn't it? Teehee. Please enjoy my dad's games!

As indicated below, the programmer's name is Ookubo Ryouichi, who had in 1985 worked on developing the NES Battle City with the small software company Tomcat Systems. That game has an Easter egg noting that the game was "WRITTEN BY OPEN-REACH WHO LOVES NORIKO", while the title screen of this game has a copyright for "OPR", presumably short for "OPEN-REACH".

The games are separated by five years, and present in this game is the nearly-three-year-old daughter of the programmer.

One-Eyed Woman

Enter the Japanese word なかしままさと (Nakashima Masato) as a Player 1 name. A small one-eyed woman will walk on-screen and shout "ま！".
