How to dump Famicom carts?

[HummerTeam1001]

Hi guys, I'd like to know how to dump Famicom games. I have some (probably) undumped generic multicarts with mostly common games on them (although one or two of them have some uncommon  pirate original games), and for fun I'd like to learn how to make ROMs from them.

I've heard you can use an Arduino to do it. I have one, but I don't know how to use it to dump games.

Any help would be appreciated. Thanks. (:

Dumping gets very complicated quickly. If you think you have anything of interest, you should message someone like CaH4e3 and see with him.

Yeah, it's not anything really anything important, it's multicarts with already dumped games. One of them has one of the Sonic Somari hacks but that's really it. I was going to maybe try dumping them as a fun project but if it's that hard then I don't think I will.
