Ok. Like this bellow? GAMEB( 2002, kof2002, neogeo, neogeo, neogeo, neogeo, kof2002, ROT0, "Eolith / Playmore", "The King of Fighters 2002 (Set 1)", 0 )
GAMEB( 2002, kof2k2nd, kof2002, neogeo, neogeo, neogeo, kof2k2nd, ROT0, "Eolith / Playmore", "The King of Fighters 2002 (Set 2)", 0 )
GAMEB( 2002, kf2k2pa, kof2002, neogeo, neogeo, neogeo, kof2k2nd, ROT0, "Eolith / Playmore", "The King of Fighters 2002 Plus (Bootleg - Set 1)", 0 )
GAMEB( 2002, kf2k2pls, kof2002, neogeo, neogeo, neogeo, kof2k2nd, ROT0, "Eolith / Playmore", "The King of Fighters 2002 Plus (Bootleg - Set 2)", 0 ) What I've found that works pretty well is to set kof2002b as the parent of the bootleg/plus games, and set kof2002 as the parent of kof2k2nd/kof2002d
