Go there download the program. If you know how to locally run BYM then do it. Its not complicated just work offline when you're working with this program.
You can easily read and redesign SWF files when working offline. Doesn't take long to change the addresses and put it back to normal, the normal window it opens up while connected to internet is 0.20 ms, using cheat engine, change that to 0.000001 and now you have 20 mins worth of time to dump any data and extract a new one.
Process requires experienced hands but once you have it =) OooCHI MAMA!
Good Luck
