See this thread:
and the images are still available here:

I can provide the scripts to build them upon request but in bfrief:
_ http://slint.fr/testing/slint64-14.1_syslinux.6.03/slint64-14.1_syslinux.6.03.img
can only be used to boot off a hard drive/USB stick
_ http://slint.fr/testing/slint64-current_goofiboot/slint64-current-goofiboot.iso
should be able to boot off an optical media but no syslinux inside
_ http://slint.fr/testing/slint64-current_efi-stub/slint64-current-efi-stub.iso
should be able to boot off an optical media but no syslinux inside
(just a kernel with an embedded initrd + command line)

I think that my next attempt will be using elilo, that can benefit
of a menu very similar to one can have with syslinux actually taking
inspiration from syslinux). Currently this just used to boot a installed
system, see:
but according to the documentation this coums also be used to boot off
an optical media.

Have a good day.
