Unused Graphics

Two alternate, and more ostentatious, copyright graphics for Nihon System.

Larger, cut-off versions of the tiny images shown in-between stages. Look at that purple hair.

A pink button stored in the sprite ROM next to the joystick sprite, and likely meant for a similar purpose.

A little visor robot with four different animations. Why this is in the sprite graphics ROM is anyone's guess, but they certainly would've made the game more interesting.

Sprite-based blocks placed in memory right after the little robot.

Version Differences

Unencrypted	Encrypted

There are at least two versions of the game; One encrypted with a Sega MC-8123 CPU module, and the other with no encryption. The encrypted one seems to be a later revision which changes the copyright graphics slightly (look at the elongated E and the spacing of the first S) as well as deleting some duplicate copyright graphics at the end of the tile graphics ROM.
