Here you will find lots of codes to your favourite Sonic games! All codes can be copied freely, even to paste them on your own webpage, no credits need to be given (with the exception of the Strategy Guides), because codes need to be shared! No chance that Sega will tell you personally, so you might as well get them from me. For you people who don't get out, the Nomad and the Mega Drive is the same thing as the Genesis.
Do you know of any codes that are not posted here? Please Email them to me!
I'll give you credit for every code you give me. I must fill up these "None Available" spots!
Problems? Please read the Codes Notice.
No glitch codes or hardware hacks will be accepted in submission.
