Keep in mind that while enhancement patches are not considered illegal, distribution of commercial game ROMs is. Therefore, the file DOES NOT include the actual Secret of Evermore game ROM. I suggest you check a search engine for other sites that may contain emulators and/or ROMs.
This patch is only intended for use on the US ROM. Versions of the game from other countries and regions are not supported and will almost certainly not work.
