The first one, from the auction description and
related pages, is single CD enclosed with (first print of?) Death Bringer for X68000, published by Telenet Japan on 1989/03/10, 9800Y.
The auction says it's 3 tracks, but the other site says 2, 黒い予感~マリオネットの笑い and Last Od'ysey. This matches what it's printed in the CD (the third line is 遊音人, a
Telenet sound team I believe)
The second one is a CD-ROM + redbook actually, so I'm not sure if we should add it.
