| Asmik released a Famicom version, 獣王記 (Jūōki), in Japan on 20 July 1990 at ¥5,900. Famicom Tsushin's release schedule of 22 June 1990 listed it as an Asmik cartridge at ¥5,900, previewed it in July as an Asmik release for 20 July at ¥5,900, and carried it on the 20th of its release schedule; a retrospective Famicom catalog gives the same date. | p. 38 (image 38), new software featureimage 202, release schedule | Magazine |
| In the Famicom manual, up on the control pad jumps and pressing it twice in a row makes a high jump; left and right move, and down crouches. A punches and B kicks. Up and A punches while jumping, up and B kicks while jumping, down and A crouches and punches, and down and B kicks enemies coming from the sky. Start starts the game, and pressed during play pauses it until it is pressed again. Famicom Tsushin's preview recommends the kick for its longer reach. | p. 38 (image 38), controls | Manual |
| Famicom Tsushin's July 1990 preview said the Famicom version, after the Mega Drive, the PC Engine, and other machines, added stages of its own: three new stages, for eight in all, with new transformation patterns, attack methods, and bosses. Its stage notes call the second stage, a dark grassland, and the fifth, a sea-floor stage, original to the Famicom version, and point out that the fifth stage's beast is a shark, not a dolphin. | p. 38 (image 38), new software featurep. 38 (image 38), new software featurep. 38 (image 38), new software featurep. 39 (image 39), comparison with earlier versions, read on the page imagep. 39 (image 39), comparison with earlier versionsp. 39 (image 39), stage 2, read on the page imagep. 39 (image 39), stage 2p. 39 (image 39), stage 5, read on the page imagep. 39 (image 39), stage 5image 85, Asmik advertisementimage 85, Asmik advertisement | Magazine |
| The same preview set the Mega Drive, PC Engine, and Famicom versions side by side. Its captions call the Mega Drive version the first port, relatively easy because difficulty can be chosen before play; the PC Engine version the most faithful to the arcade game, its difficulty kept and a little hard; and the Famicom version the easiest of the three and so easy to pick up, with sound faithful to the arcade game. | p. 39 (image 39), Mega Drive caption, read on the page imagep. 39 (image 39), PC Engine caption, read on the page imagep. 39 (image 39), Famicom caption, read on the page image | Magazine |
