R4 cards? Japan just made them illegal and ban imports, also they (whatever owns/creates R4 cards) were ordered to pay Nintendo damages.
Hmm, well I guess that's not exactly hacking the system.
Hacking should not be illegal unless the device is protected under contract law. I can respect contract law, because that's the mutual agreement I enter by using a service, HOWEVER, property rights usurp this, if I own completely and wholly 100% my device, I should be able to do with it whatever I please, that means reverse engineer it, make derivatives, sell it, modify it, etc. A lot of times (people don't realize) that user end license agreement thingy means you don't actually own your console wholly.
Ah, but I don't know about that, they want you to enter a contract after you already bought the device? Huh. You can reject I suppose, then you're free to hack to your heart's content. The unsanctioned access to the service while circumventing a contract is, well I don't know about that either.
Our system isn't the most ideal system after all, haha. Many companies unfortunately think they owe their success to IP and protecting it at all costs, I believe this is a flawed marketing strategy, a lot of people will buy your device if you make it as accessible as possible. Look at Psy for example, he didn't enforce his copyright protection when stores and shirts popped up everywhere with the names 'Gangnam Style', and it was a raving success, look at medicine, where there are on and off brand pharmaceuticals sitting right next to each other living in perfect harmony.
Surely there are MANY NUMEROUS people who bought the Wii/Brawl for the express ability of its hackability.
Oh well, maybe some day?
Hacking something you own is a just and noble thing, hacking something you do not own is criminal, but damages must be shown to convict, furthermore, no one can truly own an idea. It is unfortunate that our system thinks this. Physical property is a different story altogether, software falls under that category.
I don't even remember where I was going, oh right, hacking SSB4/Wii U/3DS. If you own it and you're not obligated under contract law to not hack it, then you should be able to. I don't know if you could though
