VTOY_TEXT_MENU_VER in grub.cfg not working?

[Premiere]

This is only used in txt mode.
For GUI mode,  it's a easter egg in the source code.

I Found that and It's very creative.
Took me about 2 days to figure most of it out and compile without changing the structure. I did need to change the array size in many places.

Its all in hex and ww. nevtoy.com the bytes are shaped.
Awesome easter egg. Been trying to compile my own words in it yet it works but will not boot the ISOs.

---

at end of all_in_one.sh I get some errors - see screenshot.
It is does not affect the  .zip file, but I just wondered if there is a problem in the sh file or maybe I am missing something?
P.S. Still not found easter egg

Did you ever get an answer for the errors in the screenshot.
I am also getting the same errors.  no such file or directory for /ISO_TMP/EFI/ventoy/ventoy.gz
As for the Xorriso cmd not found.  I installed the Xorriso package.
I get the same errors in 1.31 and 1.32 when making the live cd.

Not resolved. I assume some package is missing...

That package will build an iso file, its for the ventoy live CD.
You probably don't need it.
