From 2c89d4d5cd4e308b04cebb1c9bca48e12f0945da Mon Sep 17 00:00:00 2001 From: Subv Date: Mon, 29 Dec 2014 13:04:37 -0500 Subject: Archives: Implemented ExtSaveData and SharedExtSaveData They will be stored in /extsavedata/SDMC and /extsavedata/NAND respectively. Also redirect some APT_A functions to their APT_U equivalents. Implemented the gamecoin.dat file in SharedExtSaveData in the PTM module. Implemented formatting the savegame. Retake a previous savegame if it exists instead of reporting them as not formatted every time a game is loaded. --- src/core/hle/service/ptm_u.cpp | 47 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) (limited to 'src/core/hle/service/ptm_u.cpp') diff --git a/src/core/hle/service/ptm_u.cpp b/src/core/hle/service/ptm_u.cpp index d1498f05c..9cc700c46 100644 --- a/src/core/hle/service/ptm_u.cpp +++ b/src/core/hle/service/ptm_u.cpp @@ -3,6 +3,8 @@ // Refer to the license.txt file included. #include "common/log.h" +#include "common/make_unique.h" +#include "core/file_sys/archive_extsavedata.h" #include "core/hle/hle.h" #include "core/hle/service/ptm_u.h" @@ -11,6 +13,24 @@ namespace PTM_U { +/** + * Represents the gamecoin file structure in the SharedExtData archive + * More information in 3dbrew (http://www.3dbrew.org/wiki/Extdata#Shared_Extdata_0xf000000b_gamecoin.dat) + */ +struct GameCoin { + u32 magic; ///< Magic number: 0x4F00 + u16 total_coins; ///< Total Play Coins + u16 total_coins_on_date; ///< Total Play Coins obtained on the date stored below. + u32 step_count; ///< Total step count at the time a new Play Coin was obtained. + u32 last_step_count; ///< Step count for the day the last Play Coin was obtained + u16 year; + u8 month; + u8 day; +}; +static const GameCoin default_game_coin = { 0x4F00, 42, 0, 0, 0, 2014, 12, 29 }; +static std::unique_ptr ptm_shared_extsavedata; +static const std::vector ptm_shared_extdata_id = {0, 0, 0, 0, 0x0B, 0, 0, 0xF0, 0, 0, 0, 0}; + /// Charge levels used by PTM functions enum class ChargeLevels : u32 { CriticalBattery = 1, @@ -120,6 +140,33 @@ const Interface::FunctionInfo FunctionTable[] = { Interface::Interface() { Register(FunctionTable, ARRAY_SIZE(FunctionTable)); + // Create the SharedExtSaveData archive 0xF000000B and the gamecoin.dat file + // TODO(Subv): In the future we should use the FS service to query this archive + std::string extsavedata_directory = FileUtil::GetUserPath(D_EXTSAVEDATA); + ptm_shared_extsavedata = Common::make_unique(extsavedata_directory); + if (!ptm_shared_extsavedata->Initialize()) { + LOG_CRITICAL(Service_PTM, "Could not initialize ExtSaveData archive for the PTM:U service"); + return; + } + FileSys::Path archive_path(ptm_shared_extdata_id); + ResultCode result = ptm_shared_extsavedata->Open(archive_path); + // If the archive didn't exist, create the files inside + if (result.description == ErrorDescription::FS_NotFormatted) { + // Format the archive to clear the directories + ptm_shared_extsavedata->Format(archive_path); + // Open it again to get a valid archive now that the folder exists + ptm_shared_extsavedata->Open(archive_path); + FileSys::Path gamecoin_path("gamecoin.dat"); + FileSys::Mode open_mode = {}; + open_mode.write_flag = 1; + open_mode.create_flag = 1; + // Open the file and write the default gamecoin information + auto gamecoin = ptm_shared_extsavedata->OpenFile(gamecoin_path, open_mode); + if (gamecoin != nullptr) { + gamecoin->Write(0, sizeof(GameCoin), 1, reinterpret_cast(&default_game_coin)); + gamecoin->Close(); + } + } } } // namespace -- cgit v1.2.3
