1. CDU50E
2. CDU55D
3. CDU55E
4. CDU75E
5. CDU76E

2) Improvements:

* ver. 2.24a-->2.25a (ver. 2.25a is not released officially.)
Media Player with Windows 3.1 cannot play Enhanced CD (CD Plus) correctly.
The problem occurs when Media Player tries to play its data track as
a normal audio track.

To correct this, the command format for Enhanced CD has been changed
as outlined below. Thanks to these changes, data track is not recognized by
Media Player and the problem is resolved.
(Although audio tracks can be played correctly, other features
implemented in the Enhanced CD are not usable by Media Player.)
