Perfect Billiard may not be perfect, and it actually contains multiple billiards, but, uhh...hmm.
Unused Graphics
![]()
![]()
Two alternate, and more ostentatious, copyright graphics for Nihon System.

These are larger, cut-off versions of the tiny images shown in-between stages. Look at that purple hair.
![]()
It's a pink button. This graphic is 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 have made the game more interesting.
![]()
These are 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 of them 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.
