I exceptionally looked a little on Wipeout Pulse to find out how it is made, found nothing interesting so i looked in internet a little and found an plug-in for PSP that extracts all 3D models that are currently loaded to memory (it has to be run during game) and saves on MS in .3d (program included to convert file to .obj).
From the exctracted model i found out that the "dynamic HUD" is just transparent surface ahead of our camera with all "goodies" (speed, energy, lap time, etc.) Too bad it don't extracts textures...

Upload an model from Pulse?
