== CreateSaveDataFileSystem ==
== CreateSaveDataFileSystem ==
Takes a 0x40-byte Save-struct entry, a 0x40-byte SaveCreate-struct entry, and a 0x10-byte input struct.
Takes a 0x40-byte [[#SaveDataAttribute]], a 0x40-byte [[#SaveDataCreationInfo]], and a 0x10-byte input struct.
Only the first 0x5-bytes in the 0x10-byte struct are initialized: all-zero when automatically creating savedata during savecommon mount by official user-processes. In the dedicated save-creation code in official user-processes: +0 u32 = 0x40060, +4 u8 = 1.

Takes an input u8 [[#SaveDataSpaceId]] and a 0x40-byte Save-struct entry. Official user-process code is only known to use value 1 for the u8.
