Okay, newbie question... How comes that only certain images such as "yamaguchi.iso" give a "corrupted image" error when trying to open them in 7zip or mounting them under Windows? And what's the recommended way to open them? Bit late, I know, but I wanted to see if I could re-rip some of these with untampered and indexed palettes with Noesis.
Sorry to bump an old thread, but I just noticed that this page is also "new" - like the "Live Under the Sky" mockup, it's absent from Tom Payne's 2009 scans. Why is this noteworthy? Because it has a line art illustration of Meleon / Newtron in its missile form. This art wasn't included in the manuals, or Sonic Jam. The only place I've ever seen it is in a low quality scan from a 2014 style guide.
I wonder if the original ball sprite on this scan had more colors that the crappy 90's printer could handle.
