Well i never actually did it or know much about it so heres a few questions. Based on the name i can assume it cuts the size of a nds rom. So heres the questions: 1.Where can i get the trimming program and how does it work 2.Does it delete anything vital from the game?(I mean if it cuts the size it probally deletes some stuff from the rom the question is what) 3.Does trimming change anything in game performance? 4.Do trimmed roms work with wifi?
