NS-USBloader
~4 min read
NS-USBloader (developersu) is a PC-side Java GUI for installing NSP/NSZ to a Switch over USB (no SD removal) and for sending RCM payloads. Where TegraRcmGUI is Windows-only, NS-USBloader works on Windows, macOS, and Linux.
Features
- NSP/NSZ install — pipes to Switch-side Awoo / Tinfoil / Goldleaf over USB
- RCM payload injection — Switch in RCM + USB → one click to inject
- File transfer — push arbitrary files to Switch
- Split file joining — recombine FAT32-split XCIs
Setup
- Install Java 11+ on the PC (Adoptium / Amazon Corretto).
- Download
ns-usbloader.jar from GitHub.
- Double-click (or
java -jar ns-usbloader.jar).
- Launch the partner app on Switch (Awoo / Goldleaf) → connect USB → send from PC.
De-facto required on macOS / Linux: TegraRcmGUI is Windows-only, so for RCM payloads on Mac / Linux, NS-USBloader is your option.
Relation to the secretchat.tel loader
NS-USBloader is one of several PC-side tools for getting Atmosphère running (via RCM payload injection). Our loader requires Atmosphère, so on Erista / early Mariko without a modchip, NS-USBloader (or TegraRcmGUI) is one path. Don't use the NSP install feature — sigpatch-based NSPs on SysMMC = near-certain ban.
