It did the 03_001, 03_002, etc fine. The credits were "credits1" "credits2" etc. I try and keep the scanlation group's credits pages. Instead of being at the end of the directory, the credit pages were irregularly inserted at the beginning
See attached picture for 1 chapter of a typical manga scanlation. I also included a zip file with the first 2 chapters from the title I saw doing this. It's annoying, to say the least.
I didn't realize the resources to unzip were so small! I'd think they'd be in the megabyte range.
