From 71a063f45cba961ee07730f4ab79f2bcc3ff9b5b Mon Sep 17 00:00:00 2001 From: Subv Date: Sat, 3 Jan 2015 20:46:05 -0500 Subject: Archives: Changed the way paths are built for the archives. Each archive now takes a mount point of either NAND or SDMC, and builds its own directory structure there, trying to simulate an HLE-friendly hardware layout --- src/core/file_sys/archive_extsavedata.cpp | 14 +++++++++++--- src/core/file_sys/archive_extsavedata.h | 2 +- src/core/file_sys/archive_savedata.cpp | 15 +++++++++++++-- src/core/file_sys/archive_savedatacheck.cpp | 16 +++++++++++++--- src/core/file_sys/archive_systemsavedata.cpp | 7 ++++++- src/core/file_sys/archive_systemsavedata.h | 2 -- src/core/hle/service/cfg/cfg.cpp | 4 ++-- src/core/hle/service/fs/archive.cpp | 20 ++++++++++---------- src/core/hle/service/fs/archive.h | 5 +++++ src/core/hle/service/ptm_u.cpp | 6 +++--- 10 files changed, 64 insertions(+), 27 deletions(-) (limited to 'src/core') diff --git a/src/core/file_sys/archive_extsavedata.cpp b/src/core/file_sys/archive_extsavedata.cpp index 2f00bf067..5de2aae43 100644 --- a/src/core/file_sys/archive_extsavedata.cpp +++ b/src/core/file_sys/archive_extsavedata.cpp @@ -9,6 +9,7 @@ #include "core/file_sys/archive_extsavedata.h" #include "core/file_sys/disk_archive.h" +#include "core/hle/service/fs/archive.h" #include "core/settings.h" //////////////////////////////////////////////////////////////////////////////////////////////////// @@ -24,9 +25,16 @@ static std::string GetExtSaveDataPath(const std::string& mount_point, const Path return Common::StringFromFormat("%s%08X/%08X/", mount_point.c_str(), save_high, save_low);
