I assume you need a special device that reads N64 cartraidges to dump the ROM. I've never done any ROM dumping myself so I don't know. Its apparently legal when you make the ROM yourself, illegal to download it whether you own it or not. I still downloaded it though.
Try searching Google for "Dumping N64 ROMs". School is blocking the websites so I'm unsure of which of the links work.
I really don't understand why it's legal to dump it, but not to download it...uploading it, yes, downloading it, no.
How much does the device to dump ROMs cost? Is there any sort of risk to damage your cartridge by doing it? I know it voids your warantee, but other than that...?
I may invest in one if there's no sort of risk, and it's not too expensive. Also, if your game is broken, will that copy to the ROM as well? (Stupid question I know, just trying to make sure...) I recently bought Pokemon Crystal and it will not save at all--if I save and turn off the game, when it comes back up, "Continue" isn't an option, only "New Game" or "Options".
That's one example of where, if ROMs you dump yourself will sustain that condition, you should be able to download it. I mean, I paid money for the stupid thing and it's broken, but it's illegal for me to get a working copy of it without spending more money?
