Music Test

At the end of all versions of Ys-I when "PRESENTED BY SEGA" finishes scrolling up the screen, press Down, Right and 1 to open the music test. Use Up and Down to select a track and 1 or 2 to play it. In the Non-JP versions, you can also leave the test by scrolling down to "EXIT".

Regional Differences

Compared to the JP version, the US/EU version:

  • Uses more colors in the background.
  • Added more texture and depth to the background image. Many of the colors were made darker.
  • Redoes the color scheme in the "Ancient Ys Vanished Omen" title.
  • Changes the "Ys" logo from the Japanese to the English version (And adds a little comment beside it on how to pronounce the title).
  • Removes the black pixels in "FALCOM" and slightly edits the "C".
  • Changes the shadow color used in the font along the bottom lines.
  • Slight edits to the "G" and "A" in SEGA.

Enemy Differences

  • A handful of enemies during the earlier parts of the game were made a little easier / gave a little more experience points in the international version.
  • The names used are based off the Complete/Chronicles edition. The original manuals do have nearly-identical names, but the list is incomplete.
Name Speed Defense Experience

Looter 11 75->70 60
Rescoyd 10->9 80 70
Lyus 12->11 90->85 80

Regional Glitch

The US/EU version also introduces a new, rather obscure bug: if one goes to the Village Market with a Mirror and attempts to buy the one (at least) twice in one visit, the game will immediately glitch when the player leaves the Shop. The results vary widely, including:

  • Reset
  • Crash (either immediately or after some glitching)
  • Alternate dialogue will appear beside the portrait (usually followed up with a crash)
  • Put Adol/Aron in any map at any position with any possible inventory combination. It may even jump immediately to the closing credits.
