The famicom release of Battle Kid and The Fortress of Peril. Well almost... pretty much...kind of better actually. Siviak integrated some of the quality of life improvements that were in Battle Kid 2 in this release. As well as making some tweaks and revisions to the room layouts. A death counter is now visible and both Japanese and English are available as language options. So it is not a 1:1 duplicate to the NES counterpart, but not a sequel or remake either. Call it an improvement edition.
It was released as a CIB and is still available for purchase.
