I've compiled a list of every missing Sega Genesis game manual online here (To my knowledge):
https://www.vgcomplete.com/missing
If anyone has any of any of the listed manuals, please feel free to reach out to me. We're 80% of the way there with all the work the contributors at SegaRetro have done, but things have really slowed down.
I'm doing what I can to contribute & buying up every manual I can online but having a few helping hands wouldn't hurt!
We’ve already gotten 11 previously un-archived manuals uploaded / secured & being prepared for upload just within the last week, with many more expected on the way, but we’ll need a lot of help to complete this!
Don’t let these little booklets disappear in time ?
