Ripping sprites from Gameloft JAR games

[Omkar]

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

Can i convert source code to GDscript for Godot?

no, you cannot, from what i know GDScript is different from java
the java decompilers only convert .class to .java and i don't think a .java could be converted to GDscript
while you can write manually the java files and translate to GDscript, but it is much better to just learn java and do stuff there
