If you find a way to extract the files out of that .dat file (bmp, png and some other formats should be hidden inside it), I will reward you somehow. I really need its content to make the perfect RM2K game that this whole forum will be proud of

You think I'm joking? I'm not. I will assemble some people and attempt to make something VERY spectacular, but you'll see.
Again, I need the file content first
