open the image with winrar? i've never heard of doing that.I don't know if this is the correct file, but I'm uploading it just in case. I deleted Iris Action after extracting the CGs, as the game is massive, but I found this config.dat in the folder where I keep game updates and such.

I tried doing that but it gave me an error
