Okay, I checked the artworks that had the spacing issue that I had mentioned, and you seemed to have fixed them. Good job. Except for one... In gaunt2.zip, you have two choices, the "Widescreen Artwork" and "bezel". You managed to fix the spacing in "Widescreen Artwork", but the spacing issue still exists in the "bezel" option.
Now, I will begin downloading the rest and report any issues I find.
