Flasm is an assembler/disassembler for Flash actionscript bytecode.
Using flasm, script authors may learn how actionscript compiler and Flash Player virtual machine work, and tweak the compiled bytecode in SWF files for performance.
Cool disassembler, works great in most cases. But why does it crash if there is an encrypted protected swf?? It says:"There are too many constants!" and then stops functioning.. Great tool, keep developing ;)
