Today I found this site:
Final Fantasy Secrets
There stand something about some Warp zones. Not sure if they all usefull, maybe I must test them.
1. From Wendel Warp to Snowfield
Warp 3 (FFA)
in the woods west of Wendel, there is one screen where a road runs west to south and another road runds west to east on top of it. On the bottom road, face west. Equip any ax and go to the western limit of the screen. Make sure your limit gage is NOT full and attack to the left, at the same time moving to the left screen. You'll warp to the snowy fields.
EDIT: This one work after some tries. The important thing, you must cut the correct tree, then you warp to the Snowfield too like by my Warp. But you are near the beginning from the Snowfield.
2. A Game restart Warp?
Warp 4/5 (FFA)
in the last dungeon, there is a long zig-zag road. On the top screen, stand on the farthest place you can go without entering the forest-like place. Repeat the following until you go over the top of the screen and warp to the fire cave.
1. press up
2. press "select" while you're moving one step. (do this quickly)
3. save, reset
Use this method in the entrance to snowy fields and you don't have to get off the chocobo. (you can even enter the cave with the chocobo)
3. Warp from the Medusa Cave to the Moring Star? Wow, this must I try.
Warp2
In the cave where you get the Ice magic,
go to the corner room right before you get the ice magic.
Equip a sword, and put your will to the max.
While sliding on the two plates, do the max-move to the right.
Press left when you're flying back, and keep pressing left.
You'll warp to the cave where you get the star.
EDIT: WOW, work too. So you can get the Morning Star earlier in the game. But not sure if this is good. Because I have no idea if you can leave here.
4. Next Game restart Warp?
Warp! (FF adventure)
In the bridge that leads to the town of Wendel, do this:
1. step one up
2. While moving, and before landing onto the next step press "select"
3. Save, reset
And you'll warp to Jad after reaching the boundary of the screen.
EDIT: Work but a restart is needed.
With this I can skip too many things. Buy the Oil, Silver Cave (Megapede Fight), buy Silver Sword, Gaia Cave, Airship,
EDIT 2:
Look again my second run and found out this.
Warp from the Medusa Cave to the Moring Star will save much time, I must only get the Ice from the Medusa Cave and then warp to the next Cave. With this I can skip these things: Medusa Fight, Davias Fight and Crab Fight. And too much walking will saved. I will land in the Zyklop Golem Cave, this is the next important Cave in the game. So maybe its usefull. But I have no idea how the game will work, when I still have Amanda as friend in my group, and Lester will not be saved. That maybe something goes wrong later or I don't get the next important friend?
And I miss maybe some needed Level Ups and must defeat more enemies later.
So one last question, will this Warp accepted when I do it and it maybe work? Because it will skip 3 Boss Fights and is more a glitch and no real warp.
4 different Warp Glitche
So now after see all these Warp glitches I think I will maybe start a next run after I complete a clean run for now. So then I will do maybe 2 movies. One complete run and one glitch run. Like some other movies here on this site.
The Warps which I will maybe use are:
1. Warp from Wendel to Jadd (Game Restart Glitch)
Work, still have the girl as friend till I enter Medusa Cave, in the first screen I will have 2 Amanda's.
2. Warp from Medusa Cave to Cyklop/Golem Cave
Still have Amanda as friend. Not tested yet, but when the first part work this will to work I think.
3. Warp from Kett to Snowfield
Have Chocobo in the Snowfield.
These seems to be usefull after see all these. I hope that the game maybe not do something stupid, or I can't finish it because something is missing.
