Well, disassembling doesn’t scare me as much as it did. Which is obviously a good thing. I used the free version of IDA, and it looked like I could get some good stuff out of it (bit tired tonight though). The only thing is that it won’t look at the dos executable (i.e. the original), because it’s only a demo (the full versioin will hack into any executable you care to throw it at, by all accounts). Thankfully there is a windows executable (available from the links on the left), but I can’t help feeling that I should be using the DOS one. I imagine it to be simpler, but maybe I’m making that up.
