You can also sort your games this way (takes about 20 seconds):[*]Create a new folder at the root of your microSD card named "games2".[*]Go into your "games" folder (or wherever you keep your .nds files).[*]Do a "select all" then "cut" (CTRL-A, CTRL-X).[*]Go to your new "games2" folder.[*]Do a "paste" then "select all" then "cut" (CTRL-V, CTRL-A, CTRL-X).[*]Go back to your (now empty) "games" folder.[*]Do a "paste" (CTRL-V).[*]Delete your "games2" folder.Since none of the files are actually moving off of your microSD card, they cut/paste very quickly (it really only updates the filenames in the file table).
Of course, unless you rename the games so that they don't have numbers at the beginning of the name, 0169 will still come before 2614.
