SquareSoft/Square Enix - .dat(/.sz) movie format
Much like my lifeline_is.bms
script, this is just a proof-of-concept for "demuxing" movie data and actually extracting them as-is. Well, apart from trying to convert any kind of "audio" into GENH that is. This was originally posted on the hcs64.com message boards as its own thread, so if you want the script... well, there it is.
To be honest, I did try my best to document all there is to the script for those planning to use it in this kind of movie format but I'll try to be as brief as I possibly can here. For those who have the Japanese version of Driving Emotion Type-S, you can see through the game files that the game uses two
types of what I call "movie format": one is a paired .sz/.dat file that can store whatever chunk there is regarding both audio and video(or whatever that is), the rest(as in, the .dat files that doesn't have an accompanying .sz file at all) are just video data as far as I know. However, even a single .dat file can have its own type too as seen on Front Mission 5 in which both the video and the audio data(which in this case is a vgmstream-supported .vsf format) are stored as chunks on a single file.
That's it for now.
