Sonic Origins was, to put it politely, a bit of a mess when it launched earlier this year, and was plagued by enough presentational and technical issues - as extensively documented by Digital Foundry’s John Linneman - that its developer publicly hit out at Sega, saying it was “very unhappy” at the state the game had been launched in. Since then, Sega has been working to fix some of Origins’ more egregious problems, and its latest patch - officially known as update 1.04 - leads with an attempt to remedy a widely reported AI issue that would repeatedly cause Tails to goes off-screen in Sonic the Hedgehog 2, unable to rejoin the action. Beyond that, patch 1.04 promises a number of other miscellaneous bug fixes, plus corrections to various mislabelled soundtrack names in the museum, and an update to the Blue Sphere music that should now make it play at the correct speed. 1.04 isn’t all bug fixes however; it also makes a number of new Sonic Mania codes compatible with Sonic the Hedgehog 3’s sound test feature, as detailed by TheOcelot01 on Twitter:
