Nintendo Switch disassembly?
 

I have a number of Nintendo Switch binaries downloaded from http://debugging.games/ that claim to be builds that have symbols and stuff. They start with a header of NSO0. Does anyone know if there is a tool out there that can load these into IDA or something for disassembly and analysis? (I intend to analyze the EA APT UI library that the games I have appear to use)

Try this:
Nintendo Switch Binary loader for IDA Pro 7.0 (NRO, MOD, NSO)

Thank you for this! I will see if this plugin for IDA still works.
