Last year saw significant trouble for the emulation community, particularly with Nintendo aggressively targeting and shutting down popular emulators like Yuzu, Citra, and Ryujinx.

Despite this, no legal cases reached court, leaving the legal status of emulation largely unresolved. 

A recent discussion at the Tokyo eSports Festa enlightened this complex issue, revealing insights from top legal and intellectual property (IP) experts from major gaming companies, including Nintendo.

After going on a killing spree, Nintendo agrees emulators are legal

This aligns with broader interpretations, such as those in the US under the DMCA. However, legal complications arise when emulators circumvent technological restrictions designed to prevent piracy. 

For example, the Nintendo Switch employs measures to block unauthorized games, and bypassing these protections can breach laws like DMCA Section 1201(a)(1)(A), which prohibits circumventing technological controls.

This law, though enacted in 1998, still governs such cases today.

Emulators face additional legal challenges when replicating console-specific programs, such as menus or system software, as these are protected by copyright.

Copying these elements without authorization introduces another layer of legal vulnerability. 

Nintendo’s shutdown of emulators often stems from these violations, which the company frames as a protective measure for game developers.

A precedent exists: in 2009, Nintendo partnered with 54 developers to dismantle a device enabling pirated DS games.

Nintendo also takes issue with emulators that direct users to pirated games or distribute copyrighted materials.

Allegations against Yuzu developer Tropic Haze, who was accused of sharing ROMs for recent Switch titles, exemplify such violations. 

These actions highlight how emulators, though legally permissible, risk violation when allowing piracy or bypassing protections.

The timing of Nintendo’s heightened legal efforts may coincide with the anticipated release of the Nintendo Switch 2, expected in late 2025. 

As emulators approach compatibility with new hardware, Nintendo appears determined to curtail unauthorized access, safeguarding its IP and developers while navigating the fine line between legality and violation in emulation.
