A note about the game types - and this is important:
PitBrat created that handy installer a while ago, and it allows you to pick and choose from the literally hundreds of great mods what you want to install, then does it all for you - most of the mods don't work with the new re-release of the game because some rely on a .exe patch and the .exe is one of the only things they updated when they re-released it. If you want to mod the game quite heavily it's a good idea to use the old PC version or use the recent patch created by them to convert the new version to the old version so it's moddable.
Here is an example of my modded PC version from when we did the community playthrough - I livestreamed this.
Some of those mods are old now, but in that video it has (from memory):
- New world map (entire world retextured - looks really good in HD)
- Anniversary Avatars (For the Menu)
- Updated Font
- Battle models as field models/ remade NPC's
- Music replacement (you can pick your own or install packs)
- Weapon model replacements
- Texture replacements (for spells etc)
- Battle GUI replacement (so it's in the style of FFIX)
- Break damage/HP/MP Limit
Also note the game is played in HD, my sucky connection just causes a reduced quality when livestreaming.
Well if you're doing it manually you have to use a command-line tool called LGP/unLGP to unpack the "char" and "world" files - this creates two folders with the same name in which you put all the files. You then have to re-pack them.
So you use unLGP to unpack and create the folder from the files "char.lgp" and "world_us.lgp", drag the files in, (make sure to copy and replace), then use LGP to repack them.
The LGP format can be considered like a .zip or .rar format - it's just a compressed folder type Square created when they made the game. VIII and IX use a similar filesystem.
The files are located in the following places (in your install directory, which is normally C:\Program Files (Or Program Files (x86) if you're using a 64 bit version of windows)\Square Enix\Final Fantasy VII.
The old PC version is the same aside from being in Squaresoft, Inc. instead of Square Enix.
So within that folder, "char.lgp" is located in data/field and "world_us.lgp" is located in data/wm. Those are the files you need to unpack, replace and repack.
Alternatively, I already have the modded files so I can upload them somewhere and send you them, but it's better to learn how to do it on your own if there are other mods you're going to install in the future.
Also, be careful about asking for help on Qhimm. I've been an active member there for 10 years and there are just some very evil, evil people (as in, elitist and not helpful). It may have changed recently, I haven't been on in a while. But generally 10 years of sheer elitism speaks for itself IMO. The questions you're asking for example are usually greeted with a "DO YOU KNOW WHAT GOOGLE IS". /rant
