such an application is no more than a few C commands packed into a straightforward interface. No offense here, my point is that, and I talk by experience, with a powerfull disassembler (like IDA pro) you can extract the critical part of the code in an easy way. And at some low level, asm dump IS C source, it justs lacks variable names, but it is no more difficult than making an action replay cheat....
If you want some pointers, I could provide you the asm dump of the binary.
