It recently appeared on the auctions and I bought it. I found very few information about it here:

Translation says following:
"SNATCHER", which has been highly evaluated not only for the game itself but also for its sound, was the first "director" work of the now world-famous Director Kojima when he was affiliated with KONAMI.
This book is a so-called "MML book" that focuses only on the sound of "PC-8801 version SNATCHER", analyzes the original sound driver, and transplants the data to "MML for MUCOM88".
The main contents are as follows.
・Explanation of original "SNATCHER" sound driver commands
・Detailed explanation of SSG program drums
・More than 40 songs in MML list for MUCOM88
・All OPN tone data (text version, voice.dat dump list for MUC)
・Dump list of archived files of all MUC+α of my work
A must-have book for KONAMI sound fans and MUCOM88 enthusiasts.
134 pages (including Tables 1-4)
*It was planned to be distributed at C98, but it was not distributed due to the cancellation of the event.
