here's a little software I made that some bytecode hackers here might find useful to get their swf files. It is largely based on the old swfmdump from Mr. White. His was prone to crashing and only finds SWF files up to version 10 (latest version is 14 i believe) and for right now I would really like to dump the files from this game, but cant because his swfmdump crashes. (I am assuming it runs out of heap, but who knows). So F&*$ it, I made my own..


you can grab a copy from here on konghack (.NET 4 framework required)
swfmdump - force project x

principle:
Flash games need to be uncompressed and decrypted in memory, before flash can play them in your browser. So if you manage to get games directly from browser memory, you bypass zlib compression, mochicrypt encryption and stuff like that, and get a ready-to-hack file.

usage:

• Load your flash game entirely, then open swfmdump.exe
• Select your browser process in left list (iexplore.exe, firefox.exe, whatever)
• Hit scan button
• Select one or more swf files from the right list, based uppon file size (games will most likely size more than 1MB, these larger files are marked with a star)
• Hit dump button; your files get written in the same directory as the executable
• Reverse files in sothink decompiler or whatever tool you use

If it isn't too much of a bother, could i ask for a .NET 3.5 (or older) version, please?

I'll look into it. I dont think I use anything that would prevent that. *edit* tried to set it to 3.5. far too many errors to bother with.
?

What about unity games, does this cover them too?

ninja update. 
added better sorting for the file list.

try changing the settings to find maxSWF version of 100. if that doesnt work then youre probably targeting the wrong process.

this will now dump unity files as well as swf files
