From 13efbdc2014177b84cae82e522b191e2f2f022df Mon Sep 17 00:00:00 2001 From: Subv Date: Wed, 31 Dec 2014 19:36:50 -0500 Subject: [PATCH] SaveDataCheck: Preliminary work in this archive. This allows Steel Diver to boot further, some files are needed. This is still not ready and needs a big cleanup, this will possibly be delayed until the way we handle archives is fixed (with factory classes instead of ahead-of-time creation of archives) --- src/core/file_sys/archive_romfs.cpp | 25 +++++++++++++++++++ src/core/file_sys/archive_romfs.h | 7 +++--- src/core/hle/service/fs/archive.cpp | 37 ++++++++++++++++++++++++++--- src/core/hle/service/fs/archive.h | 1 + 4 files changed, 63 insertions(+), 7 deletions(-) diff --git a/src/core/file_sys/archive_romfs.cpp b/src/core/file_sys/archive_romfs.cpp index 2fc3831b7..df07eb657 100644 --- a/src/core/file_sys/archive_romfs.cpp +++ b/src/core/file_sys/archive_romfs.cpp @@ -5,6 +5,7 @@ #include #include "common/common_types.h" +#include "common/file_util.h" #include "common/make_unique.h" #include "core/file_sys/archive_romfs.h" @@ -23,6 +24,10 @@ Archive_RomFS::Archive_RomFS(const Loader::AppLoader& app_loader) { } } +Archive_RomFS::Archive_RomFS(std::string mountp) : mount_point(mountp) { + +} + std::unique_ptr Archive_RomFS::OpenFile(const Path& path, const Mode mode) const { return Common::make_unique(this); } @@ -67,4 +72,24 @@ ResultCode Archive_RomFS::Format(const Path& path) const { return UnimplementedFunction(ErrorModule::FS); } +ResultCode Archive_RomFS::Open(const Path& path) { + if (mount_point.empty()) + return RESULT_SUCCESS; + auto vec = path.AsBinary(); + const u32* data = reinterpret_cast(vec.data()); + std::string file_path = Common::StringFromFormat("%s%08X%08X.bin", mount_point.c_str(), data[1], data[0]); + FileUtil::IOFile file(file_path, "rb"); + + std::fill(raw_data.begin(), raw_data.end(), 0); + + if (!file.IsOpen()) { + return ResultCode(-1); // TODO(Subv): Find the right error code + } + auto size = file.GetSize(); + raw_data.resize(size); + file.ReadBytes(raw_data.data(), size); + file.Close(); + return RESULT_SUCCESS; +} + } // namespace FileSys diff --git a/src/core/file_sys/archive_romfs.h b/src/core/file_sys/archive_romfs.h index d4b1eb7f2..b657dd38b 100644 --- a/src/core/file_sys/archive_romfs.h +++ b/src/core/file_sys/archive_romfs.h @@ -20,6 +20,7 @@ namespace FileSys { class Archive_RomFS final : public ArchiveBackend { public: Archive_RomFS(const Loader::AppLoader& app_loader); + Archive_RomFS(std::string mount_point); std::string GetName() const override { return "RomFS"; } @@ -83,15 +84,13 @@ public: */ std::unique_ptr OpenDirectory(const Path& path) const override; - ResultCode Open(const Path& path) override { - return RESULT_SUCCESS; - } + ResultCode Open(const Path& path) override; ResultCode Format(const Path& path) const override; private: friend class File_RomFS; - + std::string mount_point; std::vector raw_data; }; diff --git a/src/core/hle/service/fs/archive.cpp b/src/core/hle/service/fs/archive.cpp index 9a91bcb8b..a8383d4e5 100644 --- a/src/core/hle/service/fs/archive.cpp +++ b/src/core/hle/service/fs/archive.cpp @@ -10,9 +10,10 @@ #include "common/make_unique.h" #include "common/math_util.h" -#include "core/file_sys/archive_savedata.h" -#include "core/file_sys/archive_extsavedata.h" #include "core/file_sys/archive_backend.h" +#include "core/file_sys/archive_extsavedata.h" +#include "core/file_sys/archive_romfs.h" +#include "core/file_sys/archive_savedata.h" #include "core/file_sys/archive_sdmc.h" #include "core/file_sys/directory_backend.h" #include "core/hle/service/fs/archive.h" @@ -50,6 +51,9 @@ enum class FileCommand : u32 { SetAttributes = 0x08070040, Close = 0x08080000, Flush = 0x08090000, + SetPriority = 0x080A0040, + GetPriority = 0x080B0000, + OpenLinkFile = 0x080C0000, }; // Command to access directory @@ -75,12 +79,13 @@ public: class File : public Kernel::Session { public: File(std::unique_ptr&& backend, const FileSys::Path& path) - : path(path), backend(std::move(backend)) { + : path(path), backend(std::move(backend)), priority(0) { } std::string GetName() const override { return "Path: " + path.DebugStr(); } FileSys::Path path; ///< Path of the file + u32 priority; ///< Priority of the file.
