Can you convert a large .iso to an eboot?

i'm trying to make a backup of a game that i have in case i lose it i can still play it. I've done this before, but never with such a big game. the iso is 1262 mb, and so fake_np won't convert it to an eboot. is there a program that will convert bigger isos to eboots? if not, is there anyway that i can make my iso an eboot? i have a bad habit of losing things, and this is one of my favorite games, so i'd like to be able to play it without my umd if possible. thanks in advance.
