notes: |
  Ryujinx is a standalone Nintendo Switch emulator written in C#, created by gdkchan.
  Original repo discontinued October 2024 after Nintendo takedown.
  Firmware (system NCAs) must be installed through Ryujinx's UI from a ZIP or XCI.
  Required for commercial games (.nsp, .xci). Homebrew (.nro, .nso) runs without firmware.
  Firmware provides shared fonts, timezone data, SSL certificates, system version info.
