I tried installing 64-Mate on usb stick alongside Fatdog64 using Pendrivelinux.com YUMI multiboot.  The Fatdog was on their list and installed, but wattos was not on the list.  Initially it appeared to have installed under Debian, but would not go much beyond the boot menu page.  I received an "Unable to find a medium containing a live file system modprobe: module ehci-orion not found in modules.dep"
Did I do something wrong (of course as a newbie), or should I ask Pendrivelinux.com to compile wattos into their program?
