NOTES.EXEwhat the target does and how to work it
Saturday, and the routine is read-only. KEYMASTER.EXE builds the serial it wants out of your handle, then compares it with the one you typed.
Set your handle first (the CRACKER line up in the NFO), because the serial follows from it: change your handle and you need a different one.
Two ways in: understand the arithmetic and do it yourself, or step the routine in the debugger and catch the number as it goes past.
