How can I alphabetize my games in the menu?

The easiest and fastest way to sort your roms (takes about 20 seconds):

1. Create a new folder at the root of your microsd card named "games2".
2. Go into your "games" folder (or wherever you keep your .nds files).
3. Do a "select all" then "cut" (CTRL-A, CTRL-X).
4. Go to your new "games2" folder.
5. Do a "paste" then "select all" then "cut" (CTRL-V, CTRL-A, CTRL-X).
6. Go back to your (now empty) "games" folder.
7. Do a "paste" (CTRL-V).
8. Delete your "games2" folder.

Since none of the files are actually moving off of your microSD drive, they cut/paste very quickly (it really only updates the filenames in the file table).

There are also programs such as DriveSort that can do it, but these sometimes corrupt your microSD card. DriveSort is available here: http://www.anerty.net/software/file/DriveSort.php
