What are these funny lights in Shockwave!

Info from Philippe Tarbouriech <ptarbouriech@ea.com> from Electronic Arts, one of the Shockwave designers.

The meaning of the funny lights in the Shockwave cockpit :

The green light going up and down on the left of the cockpit represents the number of pieces being loaded from the CD-ROM.
The little colored dot on the lower right that changes color is an indication of memory fragmentation... (I am sure it will help with gameplay :)
The graph on the left is the frame rate : number of VBL per frame.
The graph on the right is the number of actors in the simulation/8, every 8 frames.

And yes, there are codes, you can get powerfull laser, smart bomb, ... and several other goodies.
