Why Are Some Famicom Carts Longer?

[okame]

I've been looking at Famicom carts on eBay, and I noticed that some of them are a few inches longer, some almost as big as an NES cart. Do they have bigger circuit boards with more chips on them, or are they just longer because they're longer? Is there an actual reason for the size difference, or is it just a company thing, not making them the 'standard' size? Does anybody out there know? I'm interested in the history of video games, not just the games themselves.

More chips.

It makes them better lovers.

Because your storage cabinet is made for classic carts so you have to keep the bigger ones outside and play them more often..... ?

That's a false assumption. They don't penetrate the cartridge slot of the famicom any better despite their greater length.

It's not the length of the cartridge, but the capacity of the chips

Hahaha! Interestingly enough some games such a Athletic World doesn't seem to be any bigger on the insides. Famicom doesn't seem to have a standard for cart shells unlike later Nintendo consoles so companies made their own designs I guess.
