This is The King of Fighters 2001 (SNK / Eolith), an official Japanese release cartridge for the Neo Geo MVS arcade system.
It is a genuine SNK cartridge shell with edge connector, as pictured, and has been confirmed working on a Neo Geo MVS test setup (see photos). It is in used condition with general shelf wear on the cartridge shell, so please review all photos closely for the exact condition.
