Provided is an nro file, which is commonly how Nintendo Switch homebrew applications are distributed. The application was built using libnx, specifically derived from the hid/read-controls sample code. The application is looking for a hard-coded sequence of button presses. If these are received, the flag is decrypted and printed to the screen. The application can be run on either a vulnerable Nintendo Switch running custom firmware or on the Yuzu Emulator. Additionally, there are plugins for both Ghidra and IDA Pro that can allow you to disassemble and analyze NRO binaries.
Follow these instructions for setting up a Nintendo Switch homebrew development environment. Then simply run make in the src/ folder.
