I recently had to decompile old software that can't be registered any more. It was in VB3, so I decompiled it with a tool I found, and then I figured out where the code is that deals with registration (searching [with a hex editor] for embedded strings in the decompiled VB3 code). What's silly is: First, I only had to change 1 byte. The second is, I couldn't figure out how to change the branch instruction to the opposite, but I got lucky and hit upon it by accident (if I recall correctly, I changed the address [eg, variable 17 instead of 18] of the registered flag not the opcode).
