I tried out NT 1.5, it's a good mod though the difficulty is a bit higher than I'm used to and even simple enemy farming seems a chore now simply because even the lowest scrubs seem to hit a lot harder so it becomes less feasible to draw out battles to steal and morph and such.
I do like the translation a lot, it makes many things clearer, and the extra scenes are nice as well. So are little tidbits like Barret smacking Cloud after the materia tutorial and walking out. That was hilarious, dunno if that was an official cut moment or something you added yourself, but either way it's gold.
I'll echo a previous poster in saying that it would be nice to have a version of NT that uses the original gameplay but with NT's translation and extra scenes. I prefer yours to the one from the Reunion mod and enjoy the vanilla gameplay experience so to have them both would be great.
I've tried uninstalling NT, and even after uninstalling FF7 and reinstalling it (and clearing out the FF7 folder completely in the process, I use the steam version converted to 1998), the changes to materia and limit breaks seem to persist. Yuffie's Landscaper, for instance, still inflicts gradual petrification, which I assume came from NT because I don't recall that being in the original. And the stat modifications from many materia still don't match what they should be in vanilla even though in kernel.bin the values are set to their defaults and not what NT changed them to.
I checked it myself in both the WallMarket editor and Black Chocobo. For example, Cover has the bonuses and penalties from NT still whereas in vanilla it's only supposed to have Vitality +1. NT is the only gameplay mod I've ever installed, the rest is just graphics and sound basically. What could be overriding the kernel.bin in FF7's data folder? Or is there another file that affects materia and limit break functions as well? Any help would be appreciated. Thanks!
