      @BloodDragoon Use this thread for support. That thread is for development.

          @hex FIXED IT MYSELF!
          Build from source on Windows:

          1. Download Git from here, while you get prompted to install, it'll ask from where you want to PATH Git, choose Windows Command Line, next, use the OpenSSL library for git, for line ending conversions, choose Windows Style Checkout, commit unix-style line endings, then, the terminal, choose MinTTY, extra options, Enable system caching and Git credencial manager.

          2. Download Apache Ant's latest version here, extract to C:\Program Files, then, open the file, double click the directory bar and copy the directory name which is: C:\Program Files\apache-ant-1.10.1, then, go to your Control Panel then go to System > Advanced Configuration, you'll see advanced options, go to the checkbox that says "System Variables" at the bottom, you'll need to create a new user variable, so, click on New, you'll see a "Name of the variable" and "Value of the variable", Name the variable ANT_HOME, and set it's value to the Ant directory, click OK, then, download the Java Development Kit here, then after that, go to the JDK installation directory which is: C:\Program Files\Java\jdk1.8.0_144, copy the directory by double clicking the directory bar again, do the same process as the Ant one, except now name it JAVA_HOME, after all of this, it's time to compile it.

          3. Now open up CMD as administrator, and follow Hex's instructions above:

          git clone https://github.com/hex007/freej2me

          cd freej2me

          ant

          Do the commands one by one, then press ENTER. It should be built successfully and located on: C:\Users\YourName\freej2me.

          Good luck! :)

            @blooddragoon Looks good. I also added the following to my path:

            c:\ant\bin
            C:\Program Files\Java\jdk1.8.0_131\bin

            For the sake of others:
            You need two environment variables, JAVA_HOME and ANT_HOME Mine are are shown below. You'll need to update the paths to match your Java and Ant installations.

            Name: JAVA_HOME Value: C:\Program Files\Java\jdk1.8.0_131
            Name: ANT_HOME Value: c:\ant\bin

              Hmm... The system path? 0_1506380878521_Java home.PNG

              Like that? I don't have a C:/ant/bin...

                @blooddragoon Your paths will be different. i.e. C:\Program Files\apache-ant-1.10.1\bin and C:\Program Files\Java\jdk1.8.0_144\bin

                Though if you're building, it must not be too important.

                    @blooddragoon You could try, though it shouldn't make any difference. Your problem is very strange. Have you managed to get anything to run?

                      @recompile No... Same thing as described, thinking of trying a Windows 7 Virtual Machine just to play with in Virtualbox.

                          @blooddragoon Try running it from the command line.

                          In Windows 8, iirc, type cmd from the start screen and open the command prompt. Navigate to the build directory (you could type the whole path, e.g. cd c:\users\blooddragon\whatever\build) and run java -jar freej2me.jar

                          Paste what it spits out. With luck, that'll be enough to solve this mystery.

                              @recompile It opened up the .jar, selected Medal of Honor 2D, that's what it outputs.

                                @BloodDragoon Do you have ShadoWalker Game? try that. That is the one we both used initially for development and I finished the entire game while testing stability. So that game definitely works all the way. Check it out and let me know

                                      @blooddragoon There it is: C:\Users\Dragonkilah!\freej2me\build

                                      There's a very old bug related to exclamation points in paths:
                                      http://bugs.java.com/view_bug.do?bug_id=4523159

                                      Try moving freej2me.jar and the game to a simply named directory off root. Something like c:\j2me and running it from there.

                                      If moving the files works, then we'll know that that's the problem.

                                            @recompile You can try to test it too. I tried on my Linux system and it crashes with file not found, same as above. This is certainly the case. The error message is exactly the same.
