History
Australian programmer
Christian Whitehead created the Retro Engine for use with a 2007
fangame entitled ''Retro Sonic'', which is based upon the original ''Sonic'' games released for the
Sega Genesis
The Sega Genesis, known as the outside North America, is a 16-bit Fourth generation of video game consoles, fourth generation home video game console developed and sold by Sega. It was Sega's third console and the successor to the Master Syst ...
. The game became notable after its release for its accuracy to the games, despite not being a
ROM hack or
modification to an existing ''Sonic'' game.
''Retro Sonic'' later merged with two other ''Sonic'' fangames, ''Sonic XG'' and ''Sonic Nexus'', to form ''Retro Sonic Nexus''.
In 2009,
Sega asked fans for ideas on a game to port to
iOS. As a response, Whitehead produced a proof-of-concept video showing Sega's 1993
Sega CD game ''

. Whitehead, along with fellow ''Sonic'' scene member Simon "Stealth" Thomley, were later commissioned to create
remakes of ''

'' and ''
Sonic the Hedgehog 2'' using the engine, released for mobile platforms in 2013.
In 2014, to celebrate the twentieth anniversary of the release of ''
Sonic 3 & Knuckles'', Whitehead and Thomley produced a proof-of-concept showing the game using the engine on an iPhone. Despite fan support, Sega did not approve of the project.
Thomley speculated that this was due to legal problems regarding the music. In 2015, Whitehead, Thomley's studio Headcannon, and PagodaWest Games collaborated on an original ''Sonic'' game using the Retro Engine titled ''
Sonic Mania'', which released August 2017, with DLC titled ''Sonic Mania Plus'' being released in July 2018.
In 2019, Whitehead, in collaboration with other members behind ''Sonic Mania'', founded a new video game studio name
''Evening Star'' In reference to the studio name, the Retro Engine initially had been renamed the Star Engine. In October 2021, Evening Star announced development was underway for a game using the Star Engine. In conjunction with this, it was announced that the Star Engine had been turned into a separate engine with a focus on 3D rendering, with the Retro Engine remaining as their 2D game engine. In January 2021, an
open-source decompilation of the Retro Engine versions of ''Sonic CD'', ''Sonic the Hedgehog'', and ''Sonic the Hedgehog 2'' were released, allowing the latter two games to be run natively on PC platforms.
The Retro Engine was also used for the compilation ''
Sonic Origins'' in 2022, which includes remakes of ''Sonic the Hedgehog'', ''Sonic the Hedgehog 2'', ''Sonic CD'', and ''Sonic 3 & Knuckles''.

Reception
Reviewers praised the Retro Engine for its performance, which has been called superior to simply
emulating the original games.
TouchArcade has referred to the remasters of ''Sonic the Hedgehog'' and ''Sonic the Hedgehog 2'' as "spectacular".
Whitehead has named games such as ''
Ristar'', ''
Knuckles' Chaotix
''Knuckles' Chaotix'' is a 1995 platform game developed by Sega for the 32X. A spin-off from the ''Sonic the Hedgehog'' series, it features Knuckles the Echidna and four other characters known as the Chaotix, who must prevent Doctor Robotnik ...
