The patch store was a std::vector<IniPatch> exported to Counters and VMManager, each walking it for the places it wanted; a 'bytes' payload was a std::vector<u8> inside each patch; the dynamic patches were copies of the game database's vectors; the parser split lines into std::vector<std::string_view>; the loaders took std::string and went through std::string buffers, std::optional and FileSystem's std::vector of results. Now: - The patches are a plain array in Patch.cpp, read through LoadedPatchCount/LoadedPatch, and applied by ApplyLoadedPatches with a mask of places, in load order as before. A payload is a malloc'd run with its length, freed by ForgetLoadedPatches, and only allocated once the line has passed every check. - The dynamic patches' entries are copied into one array of their own, a pattern run then a replacement run per patch, so a reload of the game database cannot leave them dangling. - The parser splits into five (pointer, length) fields on the stack, with the stripping and empty-field rules SplitString had, and the command table takes the same. - LoadPatchesFromZip and LoadPatchesFromDir take C strings. The zip member is inflated into a malloc'd buffer. The folder is walked with retro_opendir directly, with FindFiles's filter (files, hidden ones included, "*.pnach", sizable) and its order, and each file is read with filestream_read_file, which terminates it. The "not found" message no longer has a newline in the middle of the path. tests/patch gains a lane that links Patch.cpp against the real libretro-common directory, file and inflate code: pnach files for the CRC in either case and with suffixes beside another CRC's, a .txt, a hidden file, a directory named like a pnach and an empty folder; and archives written by Python's zipfile with the member deflated, stored under an upper-case name, only under a subfolder, and behind a comment, plus every truncation and every one-byte corruption of one. It fails if the CRC match turns case-sensitive.
