There is CopyNES for those with Windows XP 32bit,

Or there is a option to use Chris Covell's TapeDump program, Only Requires Hardware, But you have to be careful using it, and requires only a Famicom, not a NES or any Famiclones!

Better yet, Make your own solution if you may.

The kazzo you built is a decent option in my opinion. Although the firmware and scripts are challenging to grasp. If you're looking to take on the project it'd be worth while to write your own firmware for it. I plan to at some point but it's a back burner kind of project.

One of the challenges of multicast dumping is reverse engineering the mapper. Most are apparently very mmc3 like so if you can grasp mmc3 you'll probably have more luck decrypting those carts' mappers.

I use the kazzo dumped some roms(some multigames,some new mapper),and i try to improve the firmware,develop the new client(it's finished)!

So this is an option!
Later,I want to try to play cartridges on a pc emulator with this device(kazzo is too slow).

I would imagine it would work fine on an NES with disabled 10NES, for the record.

Indeed, it's even marked in red under "safety notes" #2.

A Famiclone would also probably run TapeDump just fine; it's the PowerPak that has problems with clones.

can you release a custom rom,
can :
1 specify address to write data!
2 specify read address range to read vrom via audio.
3 specify read address range to read prom via audio.

I thought TapeDump requires you to have knowledge of which mapper the game uses. Don't many multigames use obscure, custom, or most importantly undocumented mappers, rendering the technique less than reliable?

I dumped some undocumented mappers!

This is true of any dumping technique that uses the cart edge - you need knowledge of the mapper in order to switch in the correct memory to read. If you pull the ROM chips out you can obviously dump the entire contents without knowing about the mapper - but the rom image isn't very useful until you know how the mapper works anyway. Bottom line, figuring out the mapper is worth the effort.

It's an idea that I might work on someday... but I still have many things on my plate right now (including a baby...)
For now, you're better off modifying an existing mapper definition (there is a program that assembles them included in the source code directory.)
