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. If no GMK is created, execute the decompiler from the command line 'decompiler ', it should tell you what's wrong. To use the decompiler you simply drag an GM8.1 or GM8.0 executable onto the Decompiler icon and the decompilation process will begin. Source expanded on from the original GameMaker 8.0 decompiler with the new (now old) Gmk library replacing the original GMK serialization library. This is the old source code (circa 2011) for the GameMaker 8.1 decompiler.
