Sonic the Hedgehog - Tisha Mania, being a ROM hack, is likely a fan-made creation modifying various aspects of the original Sonic the Hedgehog game for the Sega Genesis. The 'Tisha Mania' title hints at potentially altered enemy behavior, level themes, or story elements—perhaps themed around a character or setting referred to as 'Tisha'. The core gameplay would still involve classic Sonic platforming but infused with unique elements implemented by the ROM hack's creators. The specific creators are likely unknown unless detailed within the hack's distribution or community forums.
