   Sudachi is a standalone Nintendo Switch emulator forked from yuzu early
   access 4176 (README.md:1-4). Keys are read from the keys directory of the user data
-  directory (src/common/fs/fs_paths.h:8-9, 18). On Windows the portable
-  build uses a user folder next to sudachi.exe when it exists, otherwise
-  %APPDATA%/sudachi (src/common/fs/path_util.cpp:90-96, CMakeLists.txt:68).
-  RetroBat creates that user folder before launching sudachi.exe -g <rom>
-  and never copies keys itself.
