First I thought DOOM was really tough. When I saw '... professional protection mode ...' message I thought my time was over. I used to crack games a lot and I thought I could crack any game, it was just a matter of time. But I don't know about protected mode much so I assumed that was a beginning of a new age - the age of games running in protected mode (maybe I'm wrong completely about DOOM, I must admit I've never tried to find out about protected mode, it's just beyond me). Last night I had nothing to do and I just decided to run DOOM under my good old cracking utility I wrote a year ago. Just for fun. The key point of this program is reprogramming interrupt controller so it still works even if tricky evil Game took over all interrupts. I expected my computer to hang first. It didn't. Then I thought DOOM was too smart to let this little tiny bastard live. That wasn't the case either. I pressed very familiar to me combination Ctrl-Enter and then Ctrl-Esc to pop-up AFD - I was inside AFD ( I used to use it 'cause it was small and good enough ), happy and confused. I tried to resume DOOM and it worked ... My point, guys, is you just reprogram interrupt controller before running DOOM to avoid such a confusion. That should be it. I'll never be able to crack your games then ( my friend will, he knows how to handle reprogrammed interrupt controllers, he's pretty cool ). Best wishes to ID, yours sincerely PVP. -- Oleg Pestovsky p...@iastate.edu
