This project is a decompilation of the 2005 Sonic The Hedgehog: Part One which is the J2ME partial port of Sonic The Hedgehog.

To run and compile the game, you should install the following:

• Java Development Kit 8 (JDK 8)
• Java Wireless Toolkit or Java ME SDK (WTK)

Also, you need to add an environment variable WTK_HOME pointing to the wtk folder (example: <WTK installation folder>\JavaME_SDK_CLDC\WTK2).

Visual Studio Code is the recommanded editor to develop on this project.

Since using Language Support for Java extension need Java 17, you need to install JDK 17. Once installed, update your environment variable JAVA_HOME to use JDK 17 and add JAVA_HOME_8 to use JDK 8. This is used by build.bat script to use the correct Java version to compile your app.

• Run .\build.bat
• You should have sonic.jar at the workspace root folder. Update the sonic.jad with your text editor and update the MIDlet-Jar-Size to the jar size (on Windows: right click on sonic.jar -> properties -> there you have size).
• Launch the game with .\run.bat

• Run .\build.bat
• Launch the emulator using .\debug.bat
• On vscode, in the Run and Debug launch the debug to attach the debugger (you can also press F5)
