I used to do this a lot with shareware using a tool called SoftICE. If you ever saw a message box along the lines of "This feature is only available in the paid version...", it was easy enough to pop the debugger, work backwards to see the conditional that causes the message, change to a nop/edit the value, put the instruction pointer back, then continue on with the paid feature. I miss SoftICE.
