And how would this work for thicker manuals with glued covers like the N64 PAL ones that incorporate mulitple languages? Taking a staple out isn't going to work for a lot of manuals.
Besides ... this site is predominantly about preserving the artwork .... covers, inlays, labels etc. While I have submitted a lot of my N64 manuals it really hasn't gone any further as Snowcone is the ONLY person able to add manuals to the site at the present time.
If you really want a manual like that there is nothing stopping you downloading one and extracting the individual jpg's out of it and joining them together to create a printable one like you are asking for. I'd probably start in the middle and work outwards myself in this situation.
