Prime Selection Vol. 1 (プライムセレクションVol.1) is a demo disc for the Sega Saturn, released exclusively in Japan. It is seemingly a somewhat little known release, and as such is difficult to come by.

The disc contains 5 video previews for Saturn games and a single level playable demo of the first level of Clockwork Knight: Pepperouchau no Daibouken Gekan.

The demo of Clockwork Knight: Pepperouchau no Daibouken Gekan has a burn/compile date of 20 days prior to that of the Japanese retail release of the game, and as such there are a few object/enemy differences seen within the demo, among other small differences.


Clockwork Knight 2 Demo Differences

  • "Katchin' " enemies have Green pencils and not Red.
  • Egg gives a single coin instead of a bronze key.
  • "Pierron" enemies are in a formation of only 3 rather than 5, and are spaced out much further, making the 1-UP bonus via the egg impossible to do.
  • Another "Perrion" is hiding in the background and jumps out at you.
  • Just before the pit of death after the first turn of the level, there is a "Katchin' " enemy. Very easy to fall onto from above.
  • After using the wind-up stairs to walk on the climbing frame, an extra "Katchin' " enemy is placed above the first "Tick" enemy, right before the floating platforms you can jump over to.

  • Jumping off of the climbing frame there are only 4 pocket watches at first, but then rest on the way down are the same.

  • After the first wind up platforms with the Invincibility hidden in the egg, there are usually a row of 5 "Pierron", but in this version there are only 3, making the 1-UP bonus via the tree impossible to do.
  • The "Katchin' " enemy underneath the second set of wind up platforms does not instantly die when the platforms are wound, but does die when the platforms fall back inwards.
  • The egg underneath the second set of wind up platforms gives you a bronze key instead of a silver key.
  • After using the second set of wind-up stairs to walk on the second climbing frame, "Katchin' " enemies are noticed to be closer to the edge again, making getting hit easier.
