@neauoire @cancel Just checked on wikipedia there is a table listing the "maximum character storage capacity" where for binary you'll get 2953 "characters" which here seems to refer to octets. So I think the limit is 23,6 kb or 2,9 kB. left.rom on my system right now is 12kB.

Sad, I had this image in my mind of a handheld uxn device with a camera so you could scan in software from cards.
