You can download this screenpacks:http://www.4shared.com/account/file/55215628/34344d3d/CS2sasuke_-_ScreenPack_Naruto_.html

unzip with winzip
You will see this in the directory then:

You must move all the files which are in the directory data and put them in the directory data Mugen.

You must also do it for the directory font, therefore cut the files being in the repertory font and paste them in the repertory font of Mugen.

When you install a Screenpack, the file select.def is generally to
modify, you must thus put the chars of your old Screepack to the new one

When you download a screenpack, you can have another
file, for example music; in this case, you must
place the files which are in the directory music in the directory
sound of Mugen.

It may be also that when you unzip, there are files not in directories.

You will have to do this:

- place the .fnt files in the directory font

- place .mid and .mp3 files in the directory sound

- place the remainder of the files in the directory data

Now you can start Mugen and admire the new form of your game.
