Firestar track hack on WipEout PC

[kabuki]

In DOSBOX I've just tried holding down these keys in the order below at the spinning ag sys craft at the wipeout main menu.

1 Left Airbrake (z)
2 Right Airbrake (x)
3 Right arrow key
4 Fire (space)
5 Change View (tab)
6 Enter

The firestar cheat doesn't work for me. What am I not doing ?

Are there any visual or sound cues at the main menu once the key combo has been entered to say that the cheat is enabled?

Regards
