th07: reconstructing Touhou 7 retail 1.00b

th07 reconstructs C++ for the retail 1.00b executable of Touhou 7: Perfect Cherry Blossom using Ghidra analysis, the original Visual C++ .NET 2002 toolchain and byte comparisons against a user supplied game copy. The author reports that its standalone executable matches all 650,752 bytes of the original and documents replay trace comparisons.
