There are no territory lockouts on the Neo CD system. There are some territory DIFFERENCES on games, such as white blood on Samurai Shodown games, no bounce on Mai's TaTas in the Fatal Fury games, etc. in the U.S./Euro territory, vs. the Japanese territory. I think TonK is referring to installing a language switch in your Neo CD system, that lets you SELECT the territory you want to play in. As far as lockouts, all Neo CD games will play in all Neo CD consoles, regardless of their regions.
