I've got a little ditty in the works ("Kirkland's Manual Labor"), but it is *painfully slow* manually editing everything. Just a quick glance at my SNES works-in-progress section has 18,561 pages at 600dpi consuming *183GBs*. That's for the original wave of ~640 manuals. I have about 60 some odd more to scan in some day (hahaha). I plan on eventually having a 2K and 4K release- where images are scaled to either 1080 high for front-end usage, or 2160 high for archiving. Real collectors get all twitchy when you mention dpi- they fear everyone is out to make counterfeits and devalue their t0yz.

15 need better scans
4 are European placeholders
I also oddly have a bunch of UK/PAL manuals, so I'd like to eventually (hahaha) get all the "unique" titles. As with everything, I'm probably duplicating efforts of multitudes of other people who have burnt out on this type of project along the way. Luckily I had a stash of stuff from when I was hardcore into collecting back in the day. Unfortunately kids and work have completely torpedoed my pace.

As for the ratigators site, those scans really pop if you run them through a gaussian blur (.4 pixels if I remember his scanner settings) and some quick and dirty levels adjustments (black to 20?, white to like 248? and midtone to 85?- it's been awhile so I'm just guessing) in Photoshop. Chopping the Dreamcast section into individual pages turns it into 7300 files at approximately 24GB. TSOLFan unfortunately missed a few pages here and there. I need to bug him with a fixes list and see if he is still alive and kicking....
