Today is the scheduled release for the fan-made localization patch for the pc version of Ao no Kiseki. In the original order of release for kiseki (Trails) games, Ao / Azure comes right before Cold Steel 1. In terms of ingame timeline, Ao covers concurrent events that happen along with those of Cold Steel I and II. If someone is going in with no series knowledge, I would at least recommend starting with Zero no Kiseki, for which a similar fan-made localization has been available for one year now.
I'm excited as this is one of my very favorite games. I think I've done ~4 playthroughs, all with a past fan translation (for which I am very thankful). But the patch releasing today will be much more polished.
Edit: The release is now live here.
Though you linked it, I will mention that the Zero patch was updated with the release of the Ao patch. It changes a fair bit of names and what not to coincide with the NISA translation of Cold Steel IV.
I was planning on posting this, but you've been watching the info much more closely than I have it seems. I should finally dig into Zero/Ao now that both are complete with a decent translation.
