I know this thread is pretty old, but I hope you're still involved with the simulator. What version of Dev-C++ did you use to compile it? I need a 32 bit executable, but I'm getting tons of errors with the latest version of Dev-C++, even if I rename your folder as it is referenced in the makefile paths. What do I need to do to compile this under win7-32 or winXP-32 beyond loading the included .dev file? Thanks.
