Sonic 1 Delta is a project that began development in 2017. After a long development period including a “complete restart” of the hack, here's a demo for SSRG by Team Delta. This hack is made to mix features from Sonic 1's development and the REV00 build of the game, and also improves upon them. It features things like the early bright Green Hill Zone background, new sprites for Sonic, etc. The music has changed, too. This demo only has GHZ as there isn't much progress for other zones (at the moment, Spring Yard Zone is the most finished and it's not that playable), so I've "disabled" all zones except for Green Hill. This is really early in development, so expect most features to either be changed or some be removed.
