Specs and history


Grand passionné de jeux vidéo à mes heures, je suis l’heureux possesseur d’une Neo-Geo de 1991 avec trois manettes et environ 24 jeux payé en moyenne 100€ pièces à l’époque.Quand la passion pour l’arcade n’a pas de limite (hormis le porte monnaie!).

I have bought this wonderful machine at the very beginning in France (MODEL NEO-AEC serial 007444 – American) in August 1991 with Magician Lord + 1 joystick + 1 memory card for 600â?¬ !!!. I own 24 games which I paid between 100â?¬ and 150â?¬.

I have probably the best experience in videogame in my life with this machine, thanks to SNK. I never play so much on any system since the Neo Geo, the community is as strong as before, maybe more, and I decide to buy (10.09.2003) a NeoGeo CD+14 games on and on, a front loading NeoGeo CD system. I am not a great fan of fighting games because I prefer plattform action and shooting game.
