In Mega Man

Hi,
I was playing my rockman 4 the other day and was wondering if it is identical to Megaman 4 (other than the language)? I have played Megaman 2,3, & 6; never the fourth one. I'm just curious. Thanks

I'm not 100% positive, but I think they would be. I believe all they did was change the name to it and port it to the rest of the world. I could be mistaken, though...

I'm quite sure that they are 100% the same.
Rockman is the Japanese version, Megaman the Western version.
Should be the same game bit by bit.

I've completed both Rockman 4 and Megaman 4 and never noticed any difference between the two.
