Converting a .dgp file

Question

I have a (many) .dgp files, which is an image file that I can't open with any of the usual editors. I do know that it's a fairly normal image file though, not encoded or anything like that. Just that the headers or whatnot are not incorrect. I don't really know much about this.

Is there any program that could assist me in taking part the image file and seeing the insides, or perhaps even better, automate the process for me.

Thanks.

Edit: There probably isn't a ready built converter that can be used. What I'm more looking for is some sort of app that can read image data even without the correct headers.

Edit again:

I apologize for being slow with the updates, it's only been one day! You don't have to vote me down!

Here's an example:

My DGP file is an image extracted from an old Sega Saturn game. My assignment is to figure out how to get it to a usable form even though most apps do not recognize it.

file returns: data by the way.

Thanks everyone.

Edit3:

Thanks for helping Dave Rigby, here are two more sample files: http://uploading.com/files/96WFWQBB/BG03.DGP.html http://uploading.com/files/KXE16TRT/BG06B.DGP.html

I'm not certain what dimensions these are, sorry. But they're likely to be the same, but may not be.

Answer 1

You didn't mean dpg did you? http://www.aimersoft.com/dpg-converter.html is a converter for dpg video files never heard of dgp, and all the google results i found where just misspellings of dpg.

Answer 2

So I've found a Japanese package called ninix-aya whose source code appears to be able to open DGP files. My Japanese is non-existent, so I have no clue what this program is or what it does, but it should be possible to extract the functions which operate on BGP files and open them yourself (assuming these are the same type of files that you have).

Edit:

Ok, I've had a play around with the three files you posted. I had a look at them with hexdump and they all have virtually the same 11 bytes: Files BG00.DGP and BG06B.DGP have the exactly the same first 11 bytes and in BG03.DGP the 5th byte is 7f instead of ff:

06 30 02 00 ff 44 43 01 40 00 e0

I'm guessing this is some form of header, but I can't see how it's encoded.

The remaining data looks like some kind of bitmap image, but I can't see exactly what it is - there is a definite geometric pattern in BG00.DGP; the other two files seen less ordered. Looking at it using display (from ImageMagick) I can believe they are images, but there's quite a few variables to guess at - pixal format, colour/greyscale, image size, endian etc.
