Are these the correct backs for Mega Man?
I recently bought 2 boxed copies of Mega Man, both circle seal but one had the sticker on the front. Both of these are circle seal cartridges and have the same cartridge code but one is REV-A and one isn't. Was one of the backs swapped?

Actually, with a release date of 1987, I don't think it's possible for it to have 1985 on the back.
Why not? The other way around would be impossible.
They had 1985 back on them for years.
