main's canonical-header refactor (f38d29fd08) edited the old libSceSaveData and libSceSaveDataDialog sources this branch removes, and made EventFlag.cpp, libSceNpCommon's Runtime.cpp and GuestKernelErrors.cpp include the old SaveDataCore.hpp. Those three use nothing from it and build without it, so the include is dropped. SaveDataWriteReplacement.cpp takes main's canonical header and keeps only the native path.
