What does this do?

Removes the layers of indirection regarding the static classes full of constants
Generally renames the invalid class names in a way that makes their inheritance more clear
Finds classes that inherit from the input or output packet base class

Compile Commands

First extract zlib from the zip folder, so that the current directory has a zlib-x.x.x subdirectory

$ mkdir build
$ cd build
$ cmake ..
$ make tfm_src_simple

(Note: running just make will try to compile zlib tests which may fail preventing you from compiling. That's why I recommend typing the full target name above)

Run Command

$ ./tfm_src_simple input_file.swf output_file.swf

Example

Before: decompiled with JPEX decompiler, after "rename invalid identifiers"

package
{
   public class class_546 extends class_7
   {
      public function class_546(param1:String)
      {
         super(class_134.method_2400(class_143.var_6097),class_134.method_2400(class_168.var_6705));
         var_164.writeUTF(param1);
      }
   }
}

After: decompiled with JPEX decompiler after running this tool first (rename invalid identifiers does not need to be run)

package
{
   public class PacketOut_31_5 extends PacketOut
   {
      public function PacketOut_31_5(param1:String)
      {
         super(31,5);
         buffer.writeUTF(param1);
      }
   }
}
