I believe Memblers [And probably other people.] have ROM's that you can put NROM games on a cart and make a multicart. Although, when you want to start mixing in other mapper games, you'll have to rewrite the program for them, and it's probably not worth it.

Which games were you planning to include?

No-Carrier has a multicard menu system available on his web page (along alot of other very cool thing). Pretty easy to use too!

The requirements depend on what games you want to include, specifically their size and mapper.

MottZilla made a program to do that, in this thread but the link seem to not work. That uses MMC1, and I've also made an MMC1 multicart before with simple NROM stuff. Only odd thing I ran into was wanting to play Pooyan, it's a 16kB ROM but it uses mirrored addresses for something (copy protection?). I fixed it easily though.

To do it yourself you have to know what mapper you're using, then understand how the CPU runs the game (reset vector, NMI vector, etc).

It's not the full thing (no games included), but this main part of the source shows most of what was involved. And the .NES file shows it in action.

This cart didn't even work right on my MMC1 board, turns out it was because it was some specific version of MMC1A that starts in a random bank.

MMC1 is the hardware on the cartridge, I'm not sure what you mean.

No, for some games you will _need_ the right hardware, unless you rewrote the entire game.
