Ripping sprites from Gameloft JAR games

[Omkar]

Hi,
I have a Diamond Rush .Jar that i want to extracts sprites from.
I've tried extracting the file with 7zip and there are no image files.
I found that files named 0 ; 1 ; ... are most likely where  the sprites are located but i dont seem to get to them.
Looking for any kind of help.
THANKS GUYS YOU'RE THE BEST

I Found Most if not all of Diamond Rush's Sprites(I have Ripped them from source files). I don't know how should i ask or upload those sprites.if you want to ask me for sprites you can message me.

For the interest of ripping sprites from some other of GameLoft's J2ME mobile games, how exactly did you extract the sprites from the jar file?

I decompiled the .class files, to get .java, then somehow understood how it works
in the case of Diamond rush the sprites were in .f files, so i just looked at the java code where they were being called
i have worked with java for few years now, so it was kind of easy but just takes a very long time

since diamond rush's sprites, i am trying to port some j2me games, there are various resources online which try to reverse engineer jar files to get java files and understand them
