    was added. If your PC power isn't enough, please use this.

    image quality setting of default was changed. The density of scanlines was
    changed to 70% from 30%.
  - At 640x480FullScreen, Horizonal Scanlined (& TV Mode) and Full-Stretched
    Mode, the image quality was improved. * At this mode, a stretch of screen

  * The happiness of the game is the world human race commonness. It longs for
    peace.
  * I think that it cannot do improvement & correction of the above-mentioned
    if there are many neither operation report nor defect report. Thank you
    really for you who reported.

  - The performance of these days' PC improved. So the default setting was
    made high-definition setting.
  - At the menu space of "Save State" and "Load State", "the elapsed time from
    the game start" is indicated.
    * If the save file is started with the old version (before v1.14), the
      elapsed time isn't indicated.
    * If the game is reset by [F1] key, it's possible to reset the elapsed
      time. Or, after state file of the old version is read, if you carry out
      the "File->Set Resume" menu, the elapsed time is reset.
  - A severe indication restriction mode of Sprite (at width 336 pixel mode)
    was mounted.
    * When the check is put at "CPU->Perform SpriteLimit" menu, it's
      effective. In "R-TYPE Complete CD", a flicker of sprite (character)
      becomes the same motion (intense flicker more the "R-Type I" of Hu-CARD)
      as a real machine.
  - The speed and timing were brought close to the movement of a real machine.
    In "Metal Angel", the problem which cannot start a game (from v2.58) was
    solved.
  - Additionally, a detailed part has been improved and corrected.
