Many times the logos and seals of approval and such on these pirate carts will appear blurred, or just lack that crisp-edged appearance that a legit cart has, yet still keep the actual Nintendo logo. They probably lacked the proper equipment to make such a quality case. This one went as far as to either intentionally change the name to avoid possibly getting into worse trouble, or they were just such total retards that they didn't know how to spell it.
NES carts were harder to pirate because of the extra hardware involved in doing the memory mappers. That didn't stop'em, though! Some of those carts ended up having hacked versions of the roms to run on proprietary junk, and some of which ended up being really unreliable and buggy.
What I forgot to mention is that this Advance Wars 2 cart even has the stupid mode 7 logo thing that the rom I got off the internet once has. One of them stupid things a pirate group adds into it, you know. They didn't even bother to strip it out to make it look more legit.
But just to show you that even legit Nintendo products can still use epoxy blobs, here's what the newer revision of SMB/Duck Hunt/Track Meet looks like:
It actually looks even larger here than it really is. They're very short compared to a normal cart board. And it's the scourge to a modder who wants to socket a board for other uses, but it meant lower manufacturing costs for Nintendo, for carts they needed to mass-produce in huge quantities. We all know you can find the various SMB carts a dime a dozen. This is partially why! Though a non-revision A cart of this game should still be usable for modding. It's hard to tell how many other later carts got manufactured this way. But you can generally tell by the weight as to whether it's actually got some chips in it, or an epoxy glob.
