What a fantastic mod! great and job and thanks so much!
is there a list or a walkthrough on exact changes or side-quests etc IN ORDER ?
I saw the ReadMe file, I use it as a guide but a lot of times it's confusing. You need to go all over it to figure out what's what and you don't know when things happen. Also it seems like they some info are from previous versions (I'm playing v1.5) which makes it ever more complicated.
I'm talking about a list/walkthrough or something similar that tells you what to do and when to do it as to not waste time.
in any case the mod is simply brilliant
Here's a rough progression guide:
On Disc 3, head for the bottom of the North Crater; when you reach it, this'll unlock all the Disc 3 content but you should focus on raiding the Crater first. There's a boss on each of the three routes which you should target as you grab all the stuff available. The Crater is like a hub for gaining EXP and AP, with end-game weapons available from a lot of the mobs as Steals/Drops/Morphs (you'll need a Sneak Glove from Wall Market to get the Steals; it's bought from the same NPC that sells Batteries on Disc 1). For AP, the Left-Up path is best as you can give Ethers (not Elixirs) to the Magic Pots and find Movers on that path which both give exponentially large amounts of AP.
If encounters are proving problematic, remember that they can be toggled off at the set Save Points on each route. This can make getting all the loot a lot quicker and less risky.
If not done already, also consider getting to the Ancient Forest and Sunken Gelnika to clear those out too. Chocobo Breeding/Racing can be done, but you can skip to a Gold early if you Morph a Ghost Ship in the Underwater Reactor (the see-through pipe area where you can see the fish, etc.) for a Guidebook and trade it in to the old man in Kalm; in vanilla you'd get Underwater Materia but in NT you get the Gold Chocobo for it instead.
When you've cleared out the Crater, you've got 9x Lv.4 Limit sidequests, 4 Materia Caves, Battle Square, a round-robin thing called Junon Leagues (similar to Battle Square but different format), and a sidequest called Dark Cave. Ultimate Weapons are made at the blue house near Gongaga on the world map (where Mythril Key Item is traded for Great Gospel or Gold Armlet in the vanilla game). Each one needs two weapons specific to the character (all are acquired from the Crater enemies) and a unique item that is obtained from the Disc 3 stuff mentioned above.
I'll try and put these in some sort of order but the difficulty of one will likely vary depending on the characters, set-up, etc. The ones for Cloud, Tifa, and Cid require that they be Party Leader, which can be changed in the Operations Room of the Highwind (new NPC on the right after entering the room).
Cloud Lv.4 Limit: Starts in Shinra Mansion basement, Cloud needs to be party leader. It's a 1v1 and high-specced so it might be a good idea to leave this one until later.
Barret Lv.4 Limit: Starts at the Corel Reactor, you can access the platform you need to get to from the screen where Barret dropped Dyne in his flashback (there's a part you can jump off the rail).
Tifa Lv.4 Limit: Play the piano as normal with Tifa as party leader, then head up to the Nibel Reactor. It's a 1v1 but shouldn't be as tricky as the Cloud 1v1, though best to prepare for it.
Aeris Lv.4 Limit: Head for Forgotten City central building, the stairs will have reappeared.
Red XIII Lv.4 Limit: Visit Bugenhagen and after the scene you should have a key to re-open the Cave of the Gi; head down and go to the end of it.
Yuffie Lv.4 Limit: With Leviathan Scales, go to the cave on Da Chao to clear out the flames.
Cait Sith: Not done for a Limit Break (as he doesn't have a Lv.4), but an item he needs for his Ultimate Weapon. Head for the ruins of the Temple of the Ancients.
Vincent Lv.4 Limit: This is the same as vanilla, head for Lucrecia's cave. There's two events; the initial event with his flashback, then after a certain number of battles have been fought the 2nd event will be available.
Cid Lv.4 Limit: Starts in his house talking to Shera, then the NPC at the Tiny Bronco in the yard. Then that automated item shop that shoots at you in Wall Market followed by Gongaga Reactor. Cid needs to be party leader.
Dark Cave: This starts from Dio's museum in Battle Square; talk to him then head for the Sleeping Forest past Bone Village. You'll find some NPCs hanging about on the other side, and the vine on the right can be climbed to reach the cave above. This one's lengthier so make sure to save before going in and don't overwrite your most recent save file until you're out of it as you can't leave until its finished.
Battle Square: Special Battle should unlock immediately after talking to the clerk, which is a full party thing instead of 1 character. Final Attack can be obtained like in default game. Shards can be bought here with BP which is used to make a Masamune (which can be used by any of the characters) in the same place where Ultimate Weapons are made.
Extra Battle: In Battle Square there's an NPC on the left who has some additional fights to try. The Silver, Gold, and Platinum give W-Summon, W-Magic, and W-Item respectively but the last two fights are very highly specced. The Diamond match doesn't give anything and is there for as an optional challenge. Silver can probably be attempted early but leave the rest until later.
Materia Caves: There's four, with Red being the toughest one. Beating Blue helps with the Purple cave.
Junon Leagues: Accessed from Junon, the 'Respectable Inn' (or Beginner's Hall II). Talk to the soldiers in black there and you can send one character off into a 2-round tournament. You don't have to win every battle, just score enough points to be 1st at the end of the 2 rounds (you fight each enemy twice). Luck, Magic, and Speed Plus are the first-clear prizes for each tier.
I think that's it.
