And my dog.
I was working on Mednafen, but I'm a novice programmer and I think it's beyond my ability. This is my movie.cpp: http://pastebin.com/f7e02bb40 Mednafen starts movies from a savestate, embeds loaded savestates into the movie file and loads them during playback, and also saves a state to the end of a movie file. That movie.cpp records and plays back from power-on, and doesn't embed any savestates into the movie file. I also made it so that Mednafen doesn't compress movie files. I wanted to avoid a lot of filestream opening/closing stuff by keeping the movie in a buffer, but I can't get MDFNMOV_AddJoy to play from or record to a buffer properly.
I got a desync after about 39k frames with FCEUX 2.0.4 interim. Up until that point, it was a good run of a pretty meh game. I'll take a look at it with an older version of FCEU to see if I can get it to sync properly a little later.
[and then 3 people who always vote 10/10 votes and it drags your average down, wouldn't it be preferable in that case that the average stays the same?
While I agree that this is a good idea, doing it exactly like that probably wouldn't be good as it would make some people who constantly rate 10/10 drag down highly rated movies.
Oh, and if the big problem here is the inflation in the average score (which I think) then it would probably not help to just make the ratings of the submission hidden until it is published. Because the main reason that the ratings have been inflated is just that more people have started to vote on movies, many of whom don't find use for numbers lower than 9, and hiding the score would not change that.
