Ok so ive tried new game with 7h+nt(iro game story) + r03 exe installer, just to see what goes. It appears that nt part is working perfectly, in the beginners hall nt stuff is shown correctly(loaded previously saved game played wo nt mod), as in the YouTube video "new threat mod 1.3 (anti-anima) ep 1- a threatening start" around 34th minute, the tutorial in my game is the same as in video tutorial. The game is nt faithfull u till i beat scorpion 2nd time, didnt go further.
On the other hand ive seen many dialogues ingame so far (started great glacier in disc 2) and there is definitely a lot of changes in dialogue, presumably from r03. Few glitches such as game crashing when i enter sleeping man in the cave north of fort condor (with this install set but wo active nt mod), or not being able to get a second beta from zolom (when he hits yuffie with his tail she freezes and any action i take w other characters freezes commands and game just hangs - this also wo active nt mod), but overall its mostly smooth sailing. :-/
Maybe this will work as is...? Will reinstall to see if those glitches dissappear if yes it will be great. Maybe it would work even better w 2.0 who knows...
Edit: well sleeping man cave still crashes. Cant confirm zolom bug bc he flushes me out of battle, suppose it would also stay the same with present setup.
Maybe try full clean and reinstall all to see if it sorts those bugs.
Edit 2: It could be that it works so well bc r03 is installed and then nt is loaded via 7h on top of it? Just thinking aloud. It may serve some purpose to someone here.
