Java games for mobile phones are in .jar extensions. This file can run in mobile phones but cannot run in computers. It is not possible to run .jarÂ gameÂ files in your mobile useless you install 3rd party software. There are some emulators for running mobile jar files, among them I choose kemulator.Â Although it’s development is stopped it can be still used and support wide range of java games and have resolution of 240×320 . It is perfectly fine tuned for computer and have wide range of options including video record of game. This software need java run time to work which can be downloaded from here (Javaruntime).
