==== FS Limitations ==== | |||
- FSPXI allows all access types. | |||
- When used through fs:LDR by loader, FS only provides access to <code>exefs:/.code</code>. | |||
- For SelfNCCH access, the only allowed access types are "RomFS ("unspecified" [[NCCH#Content_Type|content type]], the default)" of the Base or Patch title, and "System Menu Data". Attempting to access "Save Data" results in error 0xE0E046BE, "RomFS (all [[NCCH#Content_Type|content types]])" in 0xF9604784, and "<code>exefs:/.code</code>" in 0xD9004676. | |||
