Rally Cross 2 - The Cheat "EKIRHS" that was not found publicly on the Internet until now?

I found this cheat exactly at the start right next where all the others are and after searching the Internet nothing is known about it.
Why it wasn't posted to cheat sites is just strange.
(Now this also explains that all the cheat sites copy the cheats from each other because this exact one could not have been found anywhere)
Its functions seem to be similar (or maybe exactly) the same as the "PREALL" cheat.
It unlocks all base tracks and all cars except the last 2.
No idea if there are any differences.
Even if it is just a duplicate cheat, it should be noted somewhere on the internet. Right?

Nice find. I'm not finding videos of the hidden tracks which can only be accessed by cheat code. The dev who designed hillside made a video of it but didn't put the name of the track in the title. All other tracks, I'm not finding any videos of.

You mean this video:

I have seen one of the developers posted 11 years later on old comments you made on that video.
I replied on one of his comments.
Maybe he still remembers about that.
I mean, they seemed to have not released this cheat here on purpose because if you use the PREALL cheat it breaks the game's season mode what i have shown here:

Maybe he still knows why this one cheat was not even released.
Also EKIRHS simply might just mean HIKERS but with rotated letters.
Also if you press R1 + R2 in the main menu you can see the build date is one month earlier before the game released fist in "October 31, 1998" in US.
This means the game was in its final state for an entire month lying around somewhere.

Just got an answer if you look on that video what is very interesting.
I never thought i would get an answer that fast.

Welp, noting this on the TCRF page.

It is nice that people add this stuff to the TCRF site because i myself have no idea how to do that.
I found out if you actually use the "preall" cheat it will do weird things that i show here:
czcams.com/video/5KpY6b2B3Iw/video.html
It looks like that the developers actually did not release that "ekirhs" cheat on purpose because it has basically the same effect as "preall" but without the ability to "disable" the rookie and veteran difficulty in the season mode.
If you do the "ekirhs" cheat after "preall" it also makes the rookie and veteran difficulties playable again.
I tested this on 2 different emulators with different BIOS versions and it always did the same so it must be a function of the game.
This seems to be some sort of easteregg that trolls the player by making him play the hardest difficulty with head-on ai on the last track with only the first vehicle of the game.
If interested also.
There is this very old "E3? build" of "The Getaway" on hiddenpalace that has these unfinished areas:

I will sure make a few videos about this version later.

By the way, i saw there is nothing noted for Hot Wheels - Extreme Racing on TCRF.
I made a few things about that game about unused and beta stuff.
I remember i tried to do that by myself but did not understand how to add something to the site.
