How do you do it? Please explain step by step, per emulator/case/whatever.
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.

The general technique is the same all over. You either create an SRAM using the previous movie, and then have it be used with the second movie file. Or you create an SRAM with the previous movie, then check that the SRAM embedded in the second movie file matches the first.

How do I check if it is inside the file?

Two methods: 1) Look up the format of the file and extract it. 2) Have the emulator save the SRAM when the movie is loaded (some emulators will do this automatically) Then compare.
