However, the ethical and legal implications of decrypted ROMs cannot be ignored. Nintendo, in particular, has taken a staunch stance against emulation that utilizes their proprietary code. The argument from the corporation is valid: creating, distributing, or downloading decrypted ROMs for games one does not own constitutes piracy. This activity undermines the intellectual property rights of the developers and publishers who invested time and money into creating the games. When a player downloads a decrypted ROM of a game that is currently available for sale on other platforms (such as a port on the Nintendo Switch), it directly competes with the legitimate market. The existence of these files fuels a piracy market that assumes "because I can access it digitally, I own it," bypassing the economic transaction that fuels the industry.

To understand the significance of decrypted ROMs, one must first understand the technical hurdles involved. Unlike older consoles where games were simply dumped from a cartridge to a file, the Nintendo 3DS utilized robust encryption to tie software to specific hardware. When a game is dumped from a 3DS cartridge or downloaded from the eShop, it is often encrypted with a "secure crypto engine." This encryption ensures that the game can only be played on the specific console that dumped it or, in the case of a physical cartridge, on legitimate hardware. For an emulator—a piece of software that mimics the hardware of the 3DS on a PC or phone—to run the game, this lock must be picked. A "decrypted" ROM is a game file that has had this specific encryption stripped away, rendering it a standalone file that emulators can read and execute.
