Backing up carts to roms

I would like to back up some old NES carts I have to ROM. I hear RetroUSB had a device you could use, but their website says it's "Temporarily Unavailable".

So what's the best way to back up a game from the cartridge?

Thanks

I'd recommend INL's device:

The Kazzo seems to be the previous generation of "standardized" ways of doing things. INL was selling them, but got tired of its warts. Hence naI's link.

The new dumper uses tremendously more verbose Lua scripts (relative to the original Squirrel scripts), but at least the errors aren't cryptic.

Depending of how easy is for you to modify cartridges and how much money/time you want to spend, TapeDump may be a nice option.

Just ordered the InfiniteNESLives board because I've seen that guy active on the forums. I hope it works well.

Thanks
