So I'm making My own ROM Hack, I edited the title Screen, BUT Then When I Tested It On SnesX9 There Where dots EVERYWHERE! In the Title Screen In the levels Everywhere!, How do I Fix this
Sounds like you edited the title screen graphics and edited a tile that's used elsewhere. (Probably tile F8, which is used as the default "empty" tile in levels. If that tile isn't completely blank, it'll show up everywhere.)
Look for the diagram called "title screen graphics" in this thread to see which tiles are safe to edit and which aren't.
