Unfortunately, there is not a separate manual for Demon, my apologies. I threw up the raw text on Pastebin for you though: https://pastebin.com/g8dmT0pp It will contain a few encoding lines used by Demon to display colors and handle the table of contents, but it should suffice.
The codex only shows recruitable characters. Humans such as West are not reflected in it (in much the same way a Pokedex does not, at least in the Pokemon games I played, show trainers)
Yeah; there will probably be some bugs if you change the save or records directories in ways the game isn't expecting. It didn't seem to be a good effort investment to go overboard armoring it up against problems that were very unlikely to occur during normal operation.
Thanks again! Just being able to keep the manual open while playing is a big help.
I didn't realize West was human, lol. I guess it makes sense the codex doesn't have him.
It's going slow so far, and I'm dying a lot (except I turn back time, lol), but I'm having a blast. I hope I improve enough to actually clear the game. XD
