If you need to extract and decode resources to nearly original form, use apktool: tool to extract resources from the apk It does not decompile original Java source code and works much faster. The limit on number of jobs is not applicable. Using a single development workflow the app allows you export your game directly to Windows desktop, Mac OS X, Ubuntu, Android, iOS, fireTV, Android TV, Microsoft UWP, HTML5, PlayStation 4, and Xbox One. Requiring a big budget to create beautiful looking games is now a thing of the past. GameMaker allows you to implement AAA game features.
This is the old source code (circa 2011) for the GameMaker 8.1 decompiler.Source expanded on from the original GameMaker 8.0 decompiler with the new (now old) Gmk library replacing the original GMK serialization library.
Usage
To use the decompiler you simply drag an GM8.1 or GM8.0 executable onto the Decompiler icon and the decompilation process will begin. If no GMK is created, execute the decompiler from the command line 'decompiler ', it should tell you what's wrong.

Future development

This was the original public release of the GameMaker 8.1 decompiler, uploaded now to keep in sync with the style of the new x2048 website. There are a few bugs in this version that have purposely been left in indefinitely because they act as a backdoor to prevent decompilation of some games, this technique has been passed on to developers who come to make asking how to protect their games. These may be fixed if I decide to continue development.Of course, the decompiler is licensed under MIT so anyone else is free to find and fix these bugs themselves and circulate a modified decompiler.
