Star Luster Cheats

After the title screen stops scrolling and the name starts flashing, quickly press Select, B, A, Right, Left, Up, Select, B, Down & Right before it stops flashing. If done right, you'll go to a Color selection screen for your ship and text.

There is a way to repair your ship without docking at a base. If you are very
low on energy, and any of your systems are on "NG" status, hold A + B on the
second player's controller, and use the microphone. If done correctly, a
shuttle will appear and repair your ship as usual. This only works once per
game.

In Adventure mode, if a planet or base gets damaged, it will turn black on
the map grid. If you go into an asteroid field and destroy 32 asteroids, you
will receive an Item Barrier, which will restore planets to their full
strength. Unfortunately, this does not work on bases; once they are damaged
or destroyed, that's it.
