The Nintendo DS Emulator for Windows/Mac/Linux, DeSmuME has been updated to version 0.9.6

Changelog

Users of gtk, cli and gtk-glade frontends please note that now we
have a common directory in ~/.config/desmume for config file,
saves and savestates. The old .desmume.ini will be moved
automatically with the name config but you have to move your saves
manually.

Some save files may be invalidated due to use of broken crc logic.
Back up your DSV files before using this version of the emulator or else
the game might wipe it.

Still has problems with freezing up due to misidentified save size.
