* The fade-out processing of "CD-DA sound" was modeled on a real machine. (When "Ys III" was played, the problem that the tune of CD-DA stopped after the casket was opened was solved.)
* It came to be able to operate "Music CD player" built into "System Card".
* When "F1"key(reset) was pushed while playing the CD-game, CD-ROM can be replaced.
* When "Out Run" was played, the problem that one line of the lowest has fallen into disorder was corrected.
* The volume of the sampling sound of "Wave Memory Sound" was modeled on a real machine more.
* The volume balance of "CD-DA, ADPCM, and PSG" have been elaborately adjusted.
