Made Flash.cpp *really* accurate
So I found out that the orignal EXE was compiled with Visual Studio .NET 2003, thanks to its Rich Header. With this compiler, I can create the exact same assembly code as the EXE. Using this, I found a bunch of inaccuracies in Flash.cpp, as a small test. I'll come back to this later, once the rest of the game is complete, but until then, here's a small taster.
