Nintendo: Switch V2 Softmod
A “softmod” is modifying a device’s software—typically the console’s firmware or boot process—to enable unauthorized functionality (homebrew applications, emulators, custom firmware, backups, etc.) without permanently altering (or with only reversible changes to) the hardware. On the Switch platform this usually means running unsigned code by exploiting vulnerabilities in software or in the boot process, then installing custom bootloaders and payloads that allow advanced features.
