I tried the installer, but it only made the values even farther off from the original. Then I saw what you said about it being made for ff7.exe. I've been using ff7_mo.exe because I use menu overhaul, so I after uninstalling and reinstalling the game again, I tried ff7.exe to see what would happen. It loaded the vanilla values just fine without using your installer, but when I go through ff7.mo.exe, it uses the values from before I first tried the installer. I don't know why it would be different, though. Thanks for trying to help, and I hope that installer works for some people. I might've made a mistake in thinking NT was causing the problem when it might in fact have been MO, though I don't know why that would be. I wasn't aware it changed any gameplay values, I thought it was merely a graphical mod. Anyway, thanks again for trying to help.
Any word on a translation-only version of NT with vanilla gameplay? Preferably with the modern progression for the spell names (Fire/Fira/Firaga, that sort of thing)?
