Ugh... Engrish aside, the article seems gravely misinformed.
After power on, enter the main system, the main system is invariable, it need the hardware of console to induct and load games. While starting game, it enter the cassette model, and has no connection with main system. Both NDS and NDSL console use this model.
That's just not true, and anyone who knows how PassMe worked knows that. The DS and DS Lite were initially hacked due to a vulnerability in the header. In other words, unlike what you're suggesting, these devices were not "hacked" via the same vulnerability as in your previous description, but via careful study of the firmware itself.
"Upgradable system + game induct": After power on, firstly enter the main system, and the main system is variable(upgradable). It also need hardware to induct and load games. While induct game successfully, the game has no connection with main system. Nintendo study from Sony, and use this model on DSi, DsiLL and DsiXL. It is easily to lock the r4 card or r4i card on main system. But it is impossible to change the configuration of NDS game. Many flashcards can pass the console detection by simulating the NDS Rom. What is more, since induct game successfully, the game has no connection with main system, it means, the console can't detect the flashcard any more.
First and foremost, the DSi, DSiXL/LL, DS and DS Lite boot DS games in the exact same way - it's just that the DSi and DSi XL/LL systems have a slightly different firmware which allows for adding certain headers onto a blacklist, thus impeding booting. It's DSi games that are problematic to boot. Secondly, the DS and DS Lite have updatable firmware, you just need to know how to update it. The fact that firmware updates were not distributed does not mean that it's not updatable - it is, and this option is utilized by FlashMe.
"Game bonding with system": After power on, enter the main system, the main system is veriable(upgradable). Games will be inducted and run on the main system. The main system can detect and control the game running at anytime. Nintendo 3DS console just use this model, that is why users can pause the game and back to main system by pressing the"Home" key. Obviously, this is the biggest obstacle for 3DS jailbreak.
All this means is that there is a background process of the menu working while you play - it changes nothing. If you think the DS has no background processes working then you are gravely mistaken. It's not an obstacle in hacking the system.
It is difficult to hack 3DS games, as the game process is under control of the main system..(that is why "Ridge Racers" can't run on Nintendo 3DS V2.0.0 system).
No, that's because that firmware update screwed up some system files and as far as I know this was remedied by future updates.
As we know, R4 card can run on Nintendo DS and DSi seriesconsole, as they stimulate NDS ROM to pass the system detection. But the 3DS system can detect and control the flashcard in total game process. It can lock the card at any time.
What makes you think that the DS cannot? Several games show off AP that's quite interesting - the Vuvuzella AP from Michael Jackson's Experience or the EXP AP from Pokemon all show that the binary of the game is perfectly capable to pick up whether it's booted from an original cartridge or not and it can react to that kind of detection. If the developers would so see fit, they could easily input a "Turn Off The Console" instruction into the code, it's just that it wouldn't change anything - hackers know how to break AP, mate. A DS binary has as much hardware access as a 3DS one, and I assure you that you also have access to firmware functionality since you have access to RTC, brightness settings and so on and so forth.
Also, the StreetPass and SpotPass will be locked, as 3DS system will easily detect the coherence. The Startup ROM is not same as Register ROM, then be locked.
And what makes you think that? A ROM is a ROM - the system won't know any better if it thinks it's signed properly, and... fooling the system is sort of what a hack is supposed to do.
Though there are many R4 3DS cards in the market, they are actual DSi cards, which can only run DSi games.
Please show me one R4 card that can run DSi binaries in DSi Mode. I'm eager to see your findings.
All in all, rather meh.
