This is revision A of SD Gundam Gaiden - Knight Gundam Monogatari - Ooinaru Isan for the SNES, released in Japan. The 'Rev A' designation indicates it's a later version, potentially with bug fixes or minor adjustments compared to the original release. The gameplay and story should remain consistent with the original version, but some elements may be improved. The game would still remain faithful to the SD Gundam style.
