I can confirm that it works on my setup. For the record, I've got a copy of Uru:CC, Quite a few ages added through ULM, and the flymode patch, all added before installing the MOUL ages. I'm running on Vista 32-bit. There didn't seem to be any conflicts. I used the manual copy method. Of note, the soundDecompress.exe wants to freeze at the end, but this doesn't seem to prevent the new ages from working. I couldn't figure out how to switch the seasons in Delin or control Jalek.
A Couple Observations:
Ladders and Linking books don't work. But the bahro day/night stones in Minkata do.
Relto pages do work, sometimes, if their index number is low enough to correspond to one of the Uru:CC pages. The page is blank if they don't.
Sit Regions do work.
I will admit, I was bad and used flymode to peak outside the Tetsonot pod to see if there was anything out there. I remember the huge debate when that age came out. Huh.
This does bring up a few existential questions for me:
1. How far could this be taken?
2. What are the differences between Plasma 1 and 2?
3. Why was Cyan so interested in moving the Uru engine over to Plasma 2?
4. If this can be done, what's to stop us from doing the same thing with the Myst 5 ages?
