EDIT: Solved, see #4 below

The GOG-provided manuals have 2 pages on each page (in the PDF), which is slightly inconvenient when viewing them on a 6" e-reader (ex: the Kindle). Would anyone happen to have a single-paged version of the manuals? Failing that, does anyone have the tools to do the job by hand?

I must admit that I thought the same thing the other day, it'd be really handy to have a game manual on my kindle and be able to quickly look stuff up that way

netbooks are actually very useful for that. I have my real laptop in front of me running a game, and I can have my netbook off to the side with the manual, or other relevant documents, open.

Here we go. Found a tool called BRISS that can split the pages.

True but they chew through power a LOT faster than a kindle (granted you have to have a kindle to get this benefit but still...)

I have an Asus Eee Netvertible that converts to a tablet PC, I love it just for reading stuff and using my touchscreen to scroll and zoom.
