⚠️ Security Warning: Only scan QR codes from trusted sources (GitHub, GBATemp, Reddit’s r/3dshacks). Malicious QR codes could install harmful software.
For the purpose of this article, search “3DSident GitHub joel16” or look for the official release page containing the QR code image.

Jace dropped the 3DS onto the desk mat. His heart hammered against his ribs. "I'm right here," he muttered, touching his chest. "I'm breathing."
He picked the device back up. The screen had changed. It was now displaying the Friends List, but the interface was glitched. The happy, bouncy background music was distorted, slowed down to a demonic growl.
There was only one friend on the list.

The username was [Jace_019].
