There was an extra zip file attached in the first of those posts that contained some files that tells the GeDoSato tool to do the texture replacement, because out of the box it doesn't recognise DBC as a game.
I've attached just those here, without the textures I put in that first one. So basically there's a 'cricket14' folder that goes into the config folder of the gedosato one, which tells the program to detect DBC starting and to do the texture overrides.
Seems like you've got the rest of the process right.
