This ROM hack is amazing! | Sonic the Hedgehog 1: South Island Expedition

Sonic the Hedgehog 1: South Island Expedition (formerly known as Sonic 1 Definitive) is a ROM hack based on Sonic 1 that feels like Sonic 3 & Knuckles meets Sonic 1 in its own way (in my opinion). I considered this ROM hack most impressive, in my opinion. Even if it works on the original hardware. Download: https://info.sonicretro.org/Sonic_the_Hedgehog:_South_Island_Expedition
