Eternam Mangekyou Sharingan

Ok we all want to know how to get the Eternal Mangekyou Sharingan but no one knows the full details so im thinking make this forum and we all pull what we know everything between rumors and facts and try to get this awesome boost. so far i know one fact behind getting ems which is ground proof.. you need.... Sharingan. that's all i got XD

ok some rumors i have heard are using sharingan 100 times or running MS for for a long period of time maybe a hour in one shot not sure yet more study is needed

i think its different for Uchiha clan and Hatake clan.

But i think thats just me
