What cams work best in ultimo

You don't need cams mate
all you need i cccam \ Oscam\Mgcamd

for card i say 99.9 cards work in vu+ boxes

CCCam and OSCam will do the same thing as a CAM but in software, so pretty much anything in the Vu cardreader will work.

¿ you have a lot of cards???? wow!!! if you are using a UKcard then oscam/CCcam is the one most commonly used combination.
As the ultimo is still in its infancy I don´t think there are any "full uk_ready backups" made yet--- so you´ll have to get around to do it yourself.
maybe you´ll be the first to make the fullbackup for others ;)
