They are most likely split on 2GB mark, which is where windows AVI writer breaks if you exceed that, so emulators split it before 2GB. You can view them all combined in VirtualDub if you open the first one and then open the next one using File - Append AVI segment (that would append them all). Exporting from VD won't break them at 2GB because it uses newer tech.
Warning: When making decisions, I try to collect as much data as possible before actually deciding. I try to abstract away and see the principles behind real world events and people's opinions. I try to generalize them and turn into something clear and reusable. I hate depending on unpredictable and having to make lottery guesses. Any problem can be solved by systems thinking and acting.
