I actually cannot find where does this CD come from.
One 2007 discussion post mentioned CD is packed with the first edition of the game's official guide. (The picutre above) Not very unlikely since a lot of Taiwanese soundtracks come with official guide books and I do have the game's guide, except a complete different cover.

Some more digging on the topic
A 2003 post mentioned Dynasty sold their music on their website with part of the credit. The post said Chen only composed 5 tracks, include "M03 劍影" and "M17 絕刃". Meanwhile Jiang Men Shi Zi Hou composed "M02 奔行" and "M19 古月".
