User submitted program reverse in OLLYDBG

in this video we analyze a user submitted program and we reverse engineer it to work as if it was activated. we accomplish this by applying some of the techniques we have seen in the past. in the end we take the easy way out and save a modified version of the program.. but we only change 2 bytes... if we wanted to spend the time to filter through the series of algorythms that this program uses to make a keygen, we could but this program is old enough now that it really wouldn't be worth it...
