I just downloaded Highwind, and I'm about to test it, thanks. As for me, this is what is happening:
I make a "char" folder, open LGP Tools (newest version), open char.lgp, then hit "Extract All" and direct it to the "char" folder. I wait for it to be finished, and then I check the "char" folder and it is still completely empty (the only "char" folder on my computer, let alone in the "field" folder).
So, I move the "char" folder to my desktop and repeat the process. Lo and behold, there are now just about 13,000 files in it, as there should be. Yay, now that worked. So, I move the now-full "char" back into "field", back up my char.lgp (and the other lgps to be modified), then run the NPC RP.exe, and it takes about 5 minutes and goes through all 12,6XX files, and the world_us.lgp and the chocobo.lgp, and it says "Update Complete". I then proceed to delete my char.lgp.
The program encountered no errors. So then I open LGP Tools once more, click "Create", and direct it to my "char" folder, and then call my new lgp file char.lgp. The program runs how it's supposed to, and when it's finished, there's a brand new char.lgp that is of larger file-size than the previous one, so obviously something has changed. So, I run ff7.exe, load up my game, and the models are EXACTLY the same as they used to be. NOTHING has changed.
So, is this similar to what anyone else has experienced? I posted my process so if any of you can see where I messed up, and not the programs, then you can tell me and I can fix them. For now, I'll attempt to use that Highwind thing and see if that works instead.
If anyone here can provide help to me regarding the above, I'd be forever in your debt. Also, and I realize this is off topic (but it will save me another post), if that same person has got FF7Music to work, I'd love help with that as well.
