This isn't a DOSBox question.

This may be harder than you think. While it is possible that the game developers used a common video file format (like FLI/FLC or DL) it is more likely that they modified the format in some possibly small way (thus making the file unplayable in other players). I can say that the file names don't give any information about format, but possibly opening them in a Hex Editor might give some clues (though you will need to do a lot of research in file formats to reverse engineer them). Good luck! leileilol is right however, DOSBox cannot help you with this much (though you may be able to extract game art by taking a lot of screen shots or recording in game video and editing it in video editing software (basically converting the animation to AVI format.

Maybe you can use TrID to identify that files...

Good luck with that. Try to find as much information about it as you can online, harras programmers of the game (really, they might help you or give you hints), try to decompile the game exe or try to find information in it, read the credits or any license file you can find, try to find out what the game company used in other games around the time, or what formats were common at the time the game was developed and so on... It is possible but takes a lot of time, patience and trial and error. I know because I'm in two projects that do what you have in mind and had to find out all kind of things about the game files (I'm talking about Exult and Pentagram).

Wow nice replies guys, thanks 😁

I'll keep on searching then and try out that TrID.
Didn't want to bug the programmers personally just yet because well ... it's hard enough as a game programmer on occasion 😉

PS: Whoops for posting on the wrong forum section.

I'd just recommend "strings" (or a hex editor). 😀

Looks like the contents of the files are pretty much self documenting, you'll just need to work out the structure of the "container" file. It might be a standard .CEL structure, but from a quick glance it looks a bit different though, so they might have added a byte or two to the header to break parsing by the regular tools (like sryx above mentioned).

http://www.wotsit.org/list.asp?fc=3 has a reasonable enough list of documentation for the file formats (basicly anything produced by "Autodesk Animator"/"Animator Pro"). But if you're going to open source your remake, it's probably easier just to find some open source code (with appropriate licence) that already does it and make the minor changes.
