Your release of the game is outdated, try this release based off the Clean Steam files from Jan 7th 2018, a crack for you to apply is there as well in the "CRACK" folder, the .exe doesn't have to be replaced (unless you want to use crack 2), I also have all the directx .dlls in the game folder regarding crash fixes, so it should work without admin if no driver updates are necessary, but if there are they must be performed with admin rights. Head at the links below for more info: Sonic CD useful files: http://tiny.cc/SonicCDPCUsefulFiles Crack 1: http://tiny.cc/SonicCDPCCrack1 Crack 2: http://tiny.cc/SonicCDPCCrack2 Clean Steam files: http://tiny.cc/SonicCDPCSteamFiles Or you could use Cracked/Legit Steam with the clean steam files without using a crack to play with a (dummy) Steam account at risk of being banned.
