As a disclaimer: This is not to try and enable piracy. I need to make this clear. There's a project I was looking into a couple weeks ago in regards to an N64 dev cart and possible ways to dump that cart and flash it to another. How easy is it to reflash carts to hold different roms for N64? If it's a dev cart, can it be flashed/written to a retail cart? What kinds of tools would be required here? Are there any reproduction shells or boards available for this? I took a couple searches and nothing really showed up, but a couple people have said it's not possible (not including dev carts). Any help would be greatly appreciated, as this is for a friend. I know everdrives are available, but those aren't what I'm wanting to have to use for such.
