Socket, known in Japan as Time Dominator 1st (タイムドミネーター1ｓｔ?), is a fast-paced platform game developed and published by Vic Tokai for the Mega Drive/Genesis. It was released on August 17, 1993. The game was not released in Europe or Australia.

Socket the Hedgeduck is an in-progress, unofficial port of levels and assets (art, custom objects, and more) from the Sonic clone titled "Socket/Time Dominator" to the Sonic 1 engine. (The title is a portmanteau on "Socket" and "Hedgehog", since the hack contains assets from Socket shoved into the Sonic 1 engine). It contains various standard platforming zones, bonus zones, and acts from the High Speed Zone as special stages, as well as various other advanced engine features and new content (such as an expanded music playlist with custom SMPS tunes, warp doors, a bonus and special stage zone feature, and much more). This is a v0.3 demo created specifically for the SHC'16!CREDITS:Tutorials•MarkeyJester: Old SSRG Logo•Mercury: Zone Agnostic objects•FraGag: Sonic 1 ROM Chunks guide•VladikComper: MegaPCM, PCM2DPCM Converter•Tornado: Sonic 1 Water Guide (for AZ, BZLa)•Other peopleHelp•ProjectFM, Clownacy, Nineko, MainMemory: Help with expanding ROM Chunks to $FF/Basic Q&A•LuigiXHero: Hack help and bugfixes•Firerat: Optimizations on the game's object handler and other bugfixes•Nineko: Rainbow Road song (from his publicly released SoniNeko SMPS pack, for Bonus Zone Fence FG2)•"Jakob": IRL friend bug testing on real hardware•AbysmalLeopard: Enlarged GHZ Ball and Level Select BG artToolsEditors/Misc•Techokami: Socketripper phps script and level rips at spriters-resource (this hack wouldn't exist without it!)•GenesisFan64: Socket disasm (used for directly ripping palettes and analysis)•MainMemory: SonLVL and S2NA supportArt•Clownancy (et. al.): Capt.

Sonic - The Lost Land is a hack of Sonic the Hedgehog for the Sega Mega Drive by Shadow Fire. The game is comprised of 7 levels, each filled with traps and badniks intent on bringing down Sonic once and for all. There is also a special realm consisting of 6 Chaos Emeralds. If you have collected at least 50 rings by the time you finish the level, you will see a giant ring. Jump into it to be taken to the secret realm. A dynamic palette system is set up , making each act load its own palette (à la Knuckles' Chaotix), as well as a dynamic music system, allowing each act to load its own music.

Sonic 1 Alt is a layout hack of Sonic the Hedgehog for the Sega Mega Drive by Ell678. It is notable for sporting barely any ASM edits, with the main focus being on the level layouts. Initial response to the new layouts was positive, though the altered palettes were less well received and so have been reverted for the next release.
