shared pictures of a not-for-sale SNK CD that he found at a Bookoff. The title is 子ども会 ミュージック集 but aside from that I can't really find anything about it. The only result for that name on Google is a single 5ch post dated 2010.
Apparently it's related to SNK's non-profit Nakoruru & Terry Club which sponsored children's sports activities. Perhaps the disc contains music SNK created for the events.
