It would be very useful if Ventoy would give an option to print on the screen the ISO-specific conifguration that Ventoy ends up using. I'm surprized it's not already an option considering it would probably help with debugging.

To give a use case, consider this: I tried making a boot disk manually using this stanza:

menuentry "antiX ISO" {
 loopback loop /antiX-19.3_386-full.iso
 linux (loop)/antiX/vmlinuz boot=antiX initrd=/antiX/initrd.gz iso-scan/filename=/antiX-19.3_386-full.iso quiet splasht disable=lxF --
 initrd (loop)/antiX/initrd.gz
}

It leads to a kernel panic. That same ISO file has no problems booting with Ventoy. Theoretically I should be able to find out what Ventoy is doing right so I can fix my manual config. I would be unable to replace my manual config with ventoy entirely because I must boot other operating systems (not from ISO).
