Could be this rom headerless? Romcenter detect it like .pas.

Technically, ALL No-Intro entries are headerless. Traditionally, when sites or other sources distribute ROM images that are "No-Intro" releases, they include headers but have their ROM manager of choice skip the header so it isn't removed.

Your file just lacks the header to begin with, probably. Someone distributed it that way. No-Intro can't help that. You can use a hex editor to add a header onto it, though. Probably the same header as the Japanese version of Gimmick would be good.
