Dead Moon, the USA version, is likely a localized version of the Japanese Dead Moon game released for the NEC PC-FX. As details on the original Japanese release are scarce, the specifics for the US release are also limited.  It is reasonable to assume the game genre, setting, and core mechanics were similar to the Japanese counterpart.  NEC was the hardware provider for the PC-FX. Without additional information, pinpointing the developer for the US version remains challenging.
