flasm
assembler and disassembler for Flash (SWF) bytecode
Flasm disassembles your entire SWF including all the timelines and events. Looking at disassembly, you learn how the Flash compiler works. You can also do some optimization on the disassembled code by hand or adjust the code as you wish. Flasm can then re-assemble the bytecode into a new SWF. It is also possible to embed Flasm actions in your ActionScript, making optimization of large projects more comfortable. Flasm is not a decompiler. What you get is the human readable representation of SWF bytecode, not ActionScript source. Flasm can also compress and decompress SWF files. Flasm does not and may never work with Flash 9 files since Flash 9 is a new virtual machine and support for it would mean a full rewrite.
