CXL Data Explorer allows to view texts and graphics which are in the folder where you put all uncompressed files of the game, and to open them in an external editor, but also to uncompress easily a SGBIN file.
Outils / CXL Data Explorer

Before using it, I recommend you to go in Tools / Options to set up the default folder and external editors paths.

Notice : This tool is not an editor, it changes no file.

Click on the "Browse" button to choose the folder where are all the uncompressed files if you have not already done it in otions.

The upper left window allows to change sub-folder and the lower left window allows to choose a file.

If you choose a SGBIN file, function SGBIN Unpak is available with a right click.

If you choose a text file or a picture supported by this software, you get a preview in the right window.
A right click on a file of this type allows to open this text file or picture in an external editor.

If a text file is shown in the preview window, you can select a part of the text or right click / Select all, then copy with the right mouse button / copy.
