Start antiX from an ISO with grub

I have a USB drive FAT32 that is able to startup with UEFI
on a MacBook Air, and shows a grub menu, It's for a different distribution of GNU/Linux, that didn't install properly.

I have an antiX 17.2 base iso file that I have copied to the USB in order to boot from the iso [as a loop device].

I used and can use a PowerPC (non-Intel-based) computer with no useable DVD burner nor internet, to perform the copy of the iso but can't read the iso file (reFind not compatible) as there is no ext4 FS support.

Question: What is the top level file/folder listing for antiX-17.2_x64-base.iso? OR what is the boot= option in grub2 I would use? Thanks. I couldn't find it online.

ANSWER: WITHIN GRUB2 command line you can view inside .ISOs:

grub> loopback loop0 /boot/iso/path-to-iso
!!! BUT NOW !!!
It loads up the kernel and initrd, but since it thinks it's a CD,/DVD it can't find linuxfs.

I can't edit the iso, so I'm wondering how I can configure the iso to find itself at startup without edits to the iso... Difficult I'm sure.

This from an older version, but the names should not have changed in 17.2:
