From da6d4cde567695d22fefc152d2d913f54e5ece68 Mon Sep 17 00:00:00 2001 From: Zach Hilman Date: Tue, 20 Nov 2018 17:51:00 -0500 Subject: patch_manager: Apply LayeredExeFS patches This will scan the /exefs dir for all files and then layer those on top of the game's exefs and use this as the new exefs. This allows for overriding of the compressed NSOs or adding new files. This does use the same dir as IPS/IPSwitch patch, but since the loader will not look for those they are ignored. --- src/core/file_sys/patch_manager.cpp | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) (limited to 'src/core/file_sys/patch_manager.cpp') diff --git a/src/core/file_sys/patch_manager.cpp b/src/core/file_sys/patch_manager.cpp index f56b1c773..ccc4f3061 100644 --- a/src/core/file_sys/patch_manager.cpp +++ b/src/core/file_sys/patch_manager.cpp @@ -79,6 +79,31 @@ VirtualDir PatchManager::PatchExeFS(VirtualDir exefs) const { exefs = update->GetExeFS(); } + // LayeredExeFS + const auto load_dir = Service::FileSystem::GetModificationLoadRoot(title_id); + if (load_dir != nullptr && load_dir->GetSize() > 0) { + + auto patch_dirs = load_dir->GetSubdirectories(); + std::sort( + patch_dirs.begin(), patch_dirs.end(), + [](const VirtualDir& l, const VirtualDir& r) { return l->GetName() < r->GetName(); }); + + std::vector layers; + layers.reserve(patch_dirs.size() + 1); + for (const auto& subdir : patch_dirs) { + auto exefs_dir = subdir->GetSubdirectory("exefs"); + if (exefs_dir != nullptr) + layers.push_back(std::move(exefs_dir)); + } + layers.push_back(exefs); + + auto layered = LayeredVfsDirectory::MakeLayeredDirectory(std::move(layers)); + if (layered != nullptr) { + LOG_INFO(Loader, " ExeFS: LayeredExeFS patches applied successfully"); + exefs = std::move(layered); + } + } + return exefs; } -- cgit v1.2.3
