Something Better/similar to Rominator

I downloaded Rominator off a site a while back, and was wandering if their is another programme which is Better than this.Its good, but whenever i go onto cheat update, it always fails for some reason. Also when it trims, i have a 128mb file, it only trims to, say an example of 101mb file, is this normal?I am new here and i cant find a link for a similar programme.ThanksI am using a NDSL R4 revolution 3 for Ds

The trimming: Yes it's normal, trimming merely removes excess data, sometimes it can be 1MB, other times 27 MB, but it's usually not too much.
