I've used IDA Pro quite a bit and like it a lot. One of things that it does is analyze program flow. You can assign your own labels and symbol names; it can detect subroutine boundaries and you can change the assembly syntax of constants. Disassembly is never lots of fun, but IDA makes it easier. I think that it's still possible to get the old "free" version on the web. The "pay to play" version covers a lot of processors (8- 16- 32- and 64-bit). IDA does require a bit of learning the lay of the land, but once you et started, things get easier faster. --Chuck
