Geno Pack is not a standalone game but likely refers to a collection or compilation featuring Geno, a character from Super Mario RPG: Legend of the Seven Stars. The nature of this pack is unclear; it might be a ROM hack, a collection of fan-made content, or a custom compilation of assets and levels. No official release by Nintendo or any other known game developer exists for such a product. Gameplay would depend entirely on the content within this unofficial package, potentially including various custom levels or modifications based on Geno's appearance in Super Mario RPG.
