Dragon Warrior: Text Sound Off

In Dragon Warrior's main script, text is printed to the main dialogue window with neither sound effects nor automatic line indenting until the first byte $50 (opening single quote) or $57 (one of the various space tiles) is encountered, upon which both the text printing sound effect and the automatic indenting are enabled for the remainder of the current string with no way to revert to silent, non-indented text.

This patch modifies Dragon Warrior's text engine to make it recognize the $EE byte as a control code that disables the text printing sound effect and automatic indenting. Subsequent uses of the $50 or $57 byte will re-enable these effects. Since the unmodified game does not make use of the $EE byte in its main script, this patch will be of limited interest to non-hackers.

This patch is compatible with both the PRG0 and PRG1 versions of Dragon Warrior.
