That's what I'd call broken - I've purchased the game, I shouldn't need to "fix" it by using another copy i'd have to purchase to have legally. =P
Anyways.. here's the real reason for this post -
I asked RIUM+ about the screenshots... (RIUM+ being one of the few people who was there in Choru, among other things, for a long time)
First, a disclaimer,
<kaelis> rium: mind if i post this on the forums?
<RIUM+> Sure. But make sure that they know that I am trying to remember things that're nearly nine years old now so I'm probably wrong in some of these
<RIUM+> So don't quote me TOO heavily on this

<RIUM+> First one... that's an oooold build of Ahnonay. That was taken before the age had been finished. Like, well and truly before it was finished.
<RIUM+> The one of the hood with all the people? That's Plasma 1 content. That's the old avatars.
<kaelis> indeed.
<kaelis> i noticed the /tree/ symbol below the fountain.
<RIUM+> The cleft was one of the many many iterations of the cleft that they went through... that one had many more ladders and bridges throughout it that they removed when they added in the windmill puzzle.
<RIUM+> Eder Kemo's shot is from when Eder Kemo was first released. iirc that's Steve Ogden's avatar since the age was mostly his work... I think
<RIUM+> That's from when they were transitioning to Plasma 2's engine
<RIUM+> Eder Kemo was an age designed for testing the abilities of Plasma as a tech demo age...
<RIUM+> To make sure that they had all the features that they wanted etc
<RIUM+> When those screenshots were taken it was a little further along in the transition to the current Plasma engine...
<RIUM+> The shadows and lighting at that point was a little different and I remember them tweaking that a bit
<RIUM+> Library shot... not much I can say about that; not too much has changed since then. It probably was from when there was Journeys throughout the city as well
<RIUM+> Gahreesehn control room... don't recognise that shot; may be new.
<kaelis> not new
<kaelis> note the imager >.>
<RIUM+> That image isn't still on the imager? >_>
<RIUM+> I have no idea what's "current" any more >.<
<RIUM+> I thought that was displayed once you "fixed" Gahreesehn?
<kaelis> nope
<kaelis> ..uh
<kaelis> fixed?
<kaelis> you don't fix gahreesen =P
<RIUM+> Great Tree... that shot's an ancient one iirc
<RIUM+> DIRT days.
<RIUM+> I've long had a theory that that tree model was from before/soon after Cyan acquired HeadSpin... it has a look about it that's very distinctive of the stuff when Plasma was running Glide
<RIUM+> But I don't know
<RIUM+> Cleft shot... can't remember when that one was taken. Before they put up the fence though.
