Anyone know what the NOWALLS, COLLIDE, and NOPAIN cheats do?

[ExileInParadise]

There are 3 cheat codes I can't quite figure out, but based on hints elsewhere in the executable, I can make some guesses.

It looks like you can see cheat descriptions when setting up Link Mode... but the descriptions do not show if you enter the code as a default player name.

So, the three codes that "flashed white" showing they worked, but that I could not quite figure out are:
NOWALLS - enables "Camera Mode"? --- how do you use it?
COLLIDE - enables wipEout (1) collisions?
NOPAIN - no clue, since NOFEAR is invulnerability?

The other cheat codes which I have also seen listed elsewhere on the net are:
DROIDS - fly in the rescue ships rather than normal racers
HITOMI - play the Curly end league movies
AXCEL - turn all speed pads white - serious speed boosts
CRAFTS - unlock all ships
MIRROR - enable the "Flip track on/off" menu option... lets you play your tracks in mirror image... very cool
UNLIMIT - unlimited weapons
NOFEAR - invulnerability/unlimited hyperthrust
ALLCNG - all challenges
ALLTNT - all tournaments
ALLTRACK - all circuits
PROTO - all prototype tracks
PHANTOM - unlock Phantom class

Please post any corrections or completions.
I am also curious if there are any developer access codes that could open other access into the games... like the ability to drive anywhere and look at any scenery, etc.
