Goldleaf (by XorTroll) is a multi-purpose homebrew app for the Switch. A single NRO bundles a file browser, NSP/XCI installer, USB transfer, amiibo emulation, and title manager.
Goldleaf is a standalone .nro launchable from hbmenu. Installing NSP/XCI requires CFW (e.g. Atmosphère) plus sigpatches — without them, signature checks reject unsigned titles even if the app launches.
Goldleaf and our loader are both homebrew NROs running under Atmosphère, so they share the same SD without conflict. The loader handles Apex-specific runtime; Goldleaf handles file ops + NSP installs. We strongly recommend loader users not install NSPs (no sigpatches on SysMMC) — but Goldleaf for file management alone is fine.
