Works perfectly !
This is only guaranteed to work on original system, should work on 90% of clone consoles BUT I DO NOT guarantee functionality on none of them. I know for sure it will NOT work on a RETRO FREAK and RETRON 5.

THIS GAME IS THE CONTINUATION AFTER FF ++, YOU ARE SUPOSED TO IMPORT YOU SAVE FILE FROM ++ TO START ++ WORLD OF CHAOS, SINCE ITS A PHYSICAL GAME IT IS NOT POSSIBLE TO DO SO..
YOU WILL START AT LEVEL 1 AND ENEMIES WILL KILL YOU IN 1 HIT. SO HERES THE SOLUTION
(I PERSONNALY TRIED THAT MYSELF AND I LEVELED UP SO IT IS POSSIBLE )
BOTTOM LINE TO ENJOY THAT GAME YOU WILL NEED TO GRIND AND LEVEL UP FIRST.

You will start on the northeastern-most island-continent in
front of a town. Head into the town, enter the storage building on the
east edge of town and take the stuff from the chests. Now buy whatever
weapons and armor you think you'll need from the shops and equip them.
Stop by the Inn and Save your game. Now leave town by the south exit,
and head directly south until you board the ship. Now sail south just
a bit and then east, until you round the "horn" at the east end of the
continent, and then sail directly north. You'll get into a battle, but
just run away. Don't worry if some characters get killed, that's going
to be happening a lot ;) Continue due north until you see land. Park
the ship here, and walk to the desert nearby to claim the airship. Now
you can go anywhere, but you're too weak until you've gained lots of
levels. You should probably go ahead and Save again (just use a Sleep-
ing Bag). Fly north about one screen and then west until you reach a
small island. The weakest enemies in the game are located here. Fight
these until you reach about level 10 or so. As you gain MP, you will
eventually want to buy spells. From this island, head north and ever-
so-slightly west until you reach the place where Coneria used to be.
Every spell in the game can be bought here. Anyway, once your guys are
a bit stronger, you can try fighting tougher enemies; I recommend fight-
ing river monsters now until you're about level 20. You can probably
figure the rest out on your own, so here ends the wall-of-text ;)
