Why? CFW is enough. Flashcards are overpriced and and not worth to buy imo.
I've never personally tested these sites, so I don't know really much about them and I heavily suggest researching all of them before making any purchases. I would normally suggest nds-card but they no longer seem to carry Stargate 3DS anymore.
But why should someone buy a flashcard when we can use custom firmware? Its for free and has more features as a shabby card.
Sky3DS+ and Stargate both mimic retail cartridges. They pretend to be the cartridge of the currently loaded ROM. This is why they are accepted by a 2|3DS console without CFW – but only if the signature is valid which means ROM unmodified and from the same region. Homebrew apps obviously do not have a Nintendo signature which means the console will refuse to load them. Even the official Sky3DS site states: “No homebrew at the moment” where at the moment most likely means forever.I know, but it cant run homebrew can it?
I am a collector of flashcarts and I've been waiting for Gateway, Stargate, etc. to all drop in price to add to my collection. There's an experience one can get through flashcarts that they can't get through a CFW and that's something that actually made me interested in them when they were still worth investing in. I don't own any 3DS flashcartat the moment, but that is a factor worth considering.But why should someone buy a flashcard when we can use custom firmware?
