it' s very difficult to patch the game with MS Paint, my friend...

You can edit the ball with
nFSHtool (You can find it at my site tutorials)

Extract ball.fsh

Put ball.fsh on to
nFSHtool.exe

Go to ball folder

Open 0000-3.bmp with MS Paint

Make your chandes and save it.

Change its size 64*64. save it as 0000-2.bmp

Change its size 32*32. save it as 0000-1.bmp

Change its size 16*16. save it as 0000-0.bmp

Open index.fsh with
nFSHtool.exe

Your ball.fsh is ready now !!

if you can' t Open index.fsh with
nFSHtool.exe (win 98 user) Put
nFSHtool to ball folder and Put ball.fsh on to
nFSHtool.exe

Patchers who have photoshop or another good editor, can make their ball textures.
open ball image in photoshop. (xcommon.viv/ball.fsh)
From image-mode menu select Grayscale
Then from image-mode menu select RGB
