Hey! I registered just to comment on this.
In the mod Aeris actually says "This guy a sick" now (if I remember correctly). I thought that was poking fun at the original translation... does it really need a fix?
I'll get it right one day.
Hi Sega Chief, and thanks for this awesome mod 
I'm a french dude currently enjoying it, and I was wondering if you would be ok with me translating it into french ?
Yeah, that'd be really cool. I think NT is available through a mod pack on ff7.fr that Satsuki manages but it's still currently in English.
The majority of text is handled through the tool Makou Reactor, but some parts of the text need older tools.
Wall Market for the Kernel text (equipment, spell names, etc.) for which you'll need Visual Studio Power Packs 3.0 installed.
The in-battle text for enemy names + attacks, and the occasional dialogue that shows (like the warning about Guard Scorpion's tail) is in the scene.bin.
If you run into any issues with the tools or the text, feel free to hit me up.
