Ys: Ancient Ys Vanished/Famicom Walkthrough changes

Of all conversion of Ys I, the Famicom makes the most drastic changes, containing material that is not present in any other edition. This page contains a list of all of the changes that exist in the Famicom version of Ys I.

General

 * Adol's movement is slower than in most versions. His health regeneration is also quite slow.
 * There are 24 levels of experience rather than 10. The last level is reached at 65,535 points.
 * Combat in the game is less flexible; Adol and his enemies are all 16 pixels wide, and they are restricted to movement on an 8 pixel grid. Therefore, you can only safely attack when you are exactly half-way to one side of the enemy.  There is no in-between.

Minea

 * Sara's home is located in the lower right corner of Minea, instead of the lower left corner. Her home is surrounded by a small moat.
 * You must talk to Sara a second time after receiving Sara's Crystal, or Jeba won't talk to you when you reach Zepik.
 * You will not find Reah anywhere in Minea. She does not appear until Darm Tower.

Plains

 * There is no Golden Vase to be found in the pond.
 * Entrance to Zepik is no longer above the pond, but rather below a line of trees south of the pond.
 * In the south east corner of the plains, there are four statues that resemble kings. Standing before these kings will teleport you to a location before another statue.  The statue in the lower right corner will send you to an island off to the west.

Mountain Path

 * In addition to the solid path that leads up the mountain, there are chains that connect various islands. You need to traverse them to reach the Thieves' Den.
 * Below the Thieves' Den, there is a one-way teleport from the east side of Mountain Path to west side.

Shrine

 * When fighting against the first boss, there are no flame jets present along the sides of the room. Instead, the boss teleports in, sends eight fireballs outward, and disappears.
 * Most of the treasures in shrine are rearranged. You'll find the Treasure Box key to the south of Feena's prison.
 * The teleportation goddess statues in shrine are more complicated than in the original version. To reach the second boss, you must also double back on one of the statues.
 * Although you collect the Mask of Eyes in the Shrine, you don't actually need it to collect any items or reach the boss. You can still see the enemies when you wear the mask on one of the floors of the Shrine.
 * On certain levels of Shrine, you can still see enemies when wearing the Mask of Eyes.
 * With a little effort, it's possible to reach Level 19 (10,000 experience points) by fighting the monsters on the lower level. It is highly recommended that you do this before facing the boss of the shrine.
 * When fighting the boss at the bottom of the Shrine for the first Book of Ys, you can only safely touch the tail. Adol will take damage if you touch the middle, just as you would touching the head.

Abandoned Mines
Unlike the original version, you can't immediately access the entrance to the mine. And even once you do, the entrance to the actual mine will be locked until you complete a second quest.
