You are almost 100% correct. There's one thing I'd like to point out, you only need one of the following files, "YSmenu.nds" or "TTmenu.nds." The file you choose to pick is essentially the alternative kernel you're picking! Quick tip, most people put the "TTmenu.nds" or "YSmenu.nds" in their "Games" folder because it allows you to easily access that file (you won't have to jump folders). Do you understand?Once again, a bunch of thanks for your helps, jimmyemunoz!
This is how your setup works: You boot up 1.62b and you'd go into your "Games" folder, find the "TTmenu.nds" or "TTmenu.nds" file.....you'd highlight that file and then press the "A" button and that's what will start your alternative kernel choice! But anyways, you are very welcome, and have a great day.
