And they are also in the PC version, can't remember exactly where ... and yes it's Altima VII.

I've been trying to get hold of this ptiDebug variable on the disassembly in hope this infrastructure was still in place and could be triggered but without much success

Bit of progress in Unity:

I have a ship that moves and hovers now ! but it can leave the track very easily
I need to get hold of how to constraint it close to it as well as the angles as it can become reversed ... any clues are welcome
