Sonic the Hedgehog: Sonic 1 Megamix is a fan-made modification of the classic Sega Genesis platformer, originally released in its version 3.0. This game introduces enhanced level layouts, unique character abilities, and additional gameplay features such as elemental shields and super forms. The update also includes music edits and a preferences screen. It supports an "Original Mode" that retains the classic experience with modern improvements.
This is considered a "complete" release, although not "final". It was succeeded by an incomplete "4.0b", which was ported to SegaCD, and further changes have been implemented since, although a "final" release and its date are tentative.

Note: Apply xdelta patch to US Genesis Sonic 1 ROM. The patch is in xdelta format due to shifted data which resulted in a IPS patch almost the same size as the patched ROM.
