Zaxxon's Motherbase 2000

Zaxxon's Motherbase 2000 is a sequel in a way to Zaxxon, but the player can jump into other ships to upgrade and turn the ship into something more than a one-hit-point-wonder with weak firepower.

Debugging Features#

Pro Action Replay code FF0552:0004 in the US version enables two new selections on the main menu.

Animation Mode#

The top-right number signifies which object is being selected, while the bottom-right number is the current animation frame. The bottom-left number doesn't appear to do anything.

• The D-Pad moves objects around the screen. Holding A and a direction will rotate/turn the object in that direction.
• Holding B while pressing Up or Down zoom in and out of objects.
• Holding B while pressing Left or Right rotates objects along the object's center.
• Holding C while pressing Up or Down changes the type of object viewed; changes between main game models, Wireframe versions of those models, Sprites, and additional models.
• Holding C while pressing Left or Right, changes what object is currently on the screen.
• Holding X while pressing Up or Down, stretches objects.
• Holding Y pauses the animation and allows the player to press Z to progress frame-by-frame.
• Pressing Start returns the player back to the main menu.

Stage Editor#

The second debugging option is invisible, making it a little hard to access it, and there doesn't seem to be a way out of this mode. Pressing A, B, or C will load the level's layout from the ROM, while Start loads the previous edit session's data. Left / Right change the level, but it seems to take a while for the game to recognize the button presses.

The HUD will be changed to display the following info:

• Top Row, First Column: The object chosen.
• Top Row, Second Column: The object chosen.
• Top Row, Fourth Column: Speed of the "cursor" while moving.
• Top Row, Fourth Column: Speed of the "cursor".
• Bottom Row, First Column: The object chosen.

The controls for this mode are somewhat buggy.

• A and C change between objects.
• B places the object on the screen.
• X changes the speed the player moves forward.
• Y removes the object selected.
• Holding Z moves forward in the level.
• Pressing Mode makes moving forward in the level go faster.
• Pressing Start goes back to the Stage Select menu.

Exception Handler#

If the game ever crashes, it'll display this exception handler.

Hidden Credit Strings#

Several strings are hidden in the Japanese/US ROM at the hex addresses listed below. They reference programmer Toru Kujirai.
