Here you can always find and download the most recent release of KiddEd:
All you need to run KiddEd is Java 1.6 or newer. No installation needed – just extract the files and run KiddEd.jar.
In order to edit Alex Kidd In Miracle World you will need a ROM of it. Until now KiddEd only supports version 1.1 of the game. This version is also known as Alex Kidd In Miracle World [v1].
If you’re running Windows and don’t have Java installed and don’t want to install it you can download KiddEd (with Java for Windows). It contains the Java binaries necessary to run KiddEd. After the download has finished you need to extract all files to a directory of your choice (running KiddEd directly from the zip archive won’t work). After extracting all files you can start KiddEd by running KiddEd.bat. Windows might tell you that the file could harm you but you can convince yourself that it doesn’t cause any harm by opening the file with a text editor to see that it’s only contents are
start java\bin\javaw.exe -jar KiddEd.jar %*. That means running KiddEd.bat tells Windows to start KiddEd.jar with Java.
%* means that it should pass through all arguments passed to KiddEd.bat to KiddEd.jar. This allows you to drag&drop ROM files on KiddEd.bat to make it load the rom directly on startup.
KiddEd allows editing many aspects of the game. The editing capabilities are split into several editors.
