If you're still wondering, this is meant to be printed and folded into a PocketMod. That's why the pages are upside down. The creator hasn't released a screen readable version. The A4 vs Letter files are for printing on different sized paper (most of the word vs US).

I wasn't anymore - but thanks :) I took to write all the rules in a file and will eventually set them up properly in a normal format (barring all the cool drawing stuff of course).
I read all my rules on a computer or tablet/phone - so all these pocket mod rules that is so popular these days often stops me from buying them unless they have a "normal" formatted version as well.
