For the record, I pretty much finished up the maps back in November, but sort of burned out on my umpteenth playthrough and didn't really finish checking them for errors. So while the first 70-80% of the maps are probably perfect/complete, there's probably a handful of missing or misplaced minor items, incorrect markers for how to access them, etc., left in the final areas' final maps that I sent him.
But I think I squashed all the major mistakes I made, like the Stomp Boots map that completely omitted both switches you needed to reach the item, or the Capricorn map path that directed you through multiple solid walls... It was nice to watch MeleeWizard's LP of the final area and have my guess at the correct path actually confirmed (since I never managed to beat the "final" boss and wasn't really clear which path you took through the last section - hence I made educated guesses based off the quest file.)
I was supposed to help out taking screenshots of bosses and corridors and whatnot to help fill in the guide, but, yeah well, I managed to find other stuff to do in the meantime... Sound familiar? If there actually are a lot of mistakes left in the maps after release, I'll try to find the time to go over them and fix them for an updated version of the guide, but I'm not sure it really matters that much, so long as all the major stuff is covered. It probably depends upon whether C-Dawg asks me to or not... hell, maybe some minor mistakes would just add to the charm, right?
At any rate, you should be pleased to hear I blindly stumbled into a solution for packaging it all up nicely into a single archived download that self-extracts and "installs" itself and immediately launches the quest upon extraction. (I just kept randomly messing around with stuff and googling things until I sort of figured it out.) So once I have a final copy of the quest and accompanying files, I can zip them all up in an SFX archive that will unpack the game wherever you tell it to, and add shortcut icons/menu in your Start folder and on the Desktop (any of which can be deleted if unwanted.) They'll allow the player to open the manual, strategy guide, play the soundtrack, etc., as well as launch any of the however many preloaded save slots he wants it to launch with, bypassing the ZC and TLOZ intros and main menu completely. I've had a few others test it out and they all confirmed it works splendidly on several different Windows OSs, so this should prove to be the one-click solution any fool can download and play that C-Dawg was looking for, rather than fielding the numerous questions/complains about getting it to work which the demos generated last year, on the non-ZC sites he posted it to.
It would be awesome if the stupid sideview gravity collision bug in the 2.50.1 and custom builds got fixed before release, but well I'm not holding my breath on that one... Extra frustratingly unfair controller-throwing challenge!
This is quite impressive! Nice job on the strategy guide!
