I've been trying to rip the images from the art gallery in the Collection, first uncompressing the .arc files (which all the output .tex are strangely of the same filesize) and then using RTB's Capcom MT Framework (PC and Switch) - TEX to DDS Converter for QuickBMS. (Both the PC and Switch versions of the script) but the .dds output files seem to be invalid.
