The Oregon Trail: matching Win32 executable and DLL reconstruction

This matching decompilation reconstructs C++ functions from the 1996 Windows release of The Oregon Trail, targeting Oregon32.exe and OREGON32.DLL. It compares functions compiled with Visual C++ 4.0 against the originals while accounting for relocated operands; the author reports 35,926 recovered instructions out of 64,499 inventoried.
