: If you are getting "Invalid NCA" errors on a physical Switch, switching from Goldleaf to DBI or Tinfoil can sometimes bypass installation hurdles by better handling different NSP formats.
In Switch modding slang, a or "hot install" refers to injecting or replacing an NCA while the system is running (in-memory), typically using tools like EdiZon or Tesla Overlay.
