3DS card-free refers to an accessory used in 3DS series handhelds, which is also commonly known as flash memory card or crack card. Specifically, it is a memory card. Users can load the ROM files of 3DS games into the card, and then insert the card into the handheld, so that they can start the games downloaded by the players themselves without an official game card. Because this card can bypass the restrictions of game manufacturers on handheld devices and is easy to download and use, it has a great market in some fields.

Using 3DS without a card may bring some risks. First of all, the card belongs to cracking equipment, and cracking software and hardware is considered illegal, which may violate the laws of some countries or regions. Secondly, inserting 3DS without card may damage the handheld. Because the technology used by the card is not supported by the government, it may cause some pressure and damage to the handheld device, and may even cause the handheld device to turn brick, that is to say, it can no longer be used or even restored to its original state.

Mobile phone cracking and the influence of game developers

The cracking of handheld devices will also have an impact on game developers. On the one hand, it may reduce their income, because users can get free games, and game developers may not get any benefits from these illegal uses. On the other hand, cracking may also damage the quality of the game. Making and distributing game ROM files without authorization may cause players to encounter some problems, such as the stability and playability of the game may be affected.
