Thats the same with everything though. With patience you can do almost anything to do with hacking. Anyway, I said not bad for a few reasons. 1. I consider myself not bad, but not great. 2. Its not about inserting, its also about changing the colours n the pallette, what each tile does (ie warp tiles), how the background works. I say that the greatest Tile Inserter can create new tilesets, and that is something that not many can do...
