If you installed the game using the native setup program, you might need to change the security settings of the folder to Full control for your Windows account before patching the game.

SimCity Classic Patch zip file with patch.bat is hereīoth patches require bspatch.exe from here. I then applied the same changes to the SimCity Classic Terrain Editor executable and then patched the EXE files with OllyDbg.Ĭraz圜asta’s SimCity 2000 Patch is here and the packaged zip file with patch.bat is here I fired up the program with the modifications and sure enough the File Open and File Save windows appeared and functioned correctly. I then compared the flags passed in an unpatched and patched SimCity 2000 executable and changed the flags in the SimCity Classic executable to match the patched SimCity 2000 executable. This information allowed me to create patches for SimCity Classic for Windows 95, a true 32-bit version of the original SimCity.Īfter hours of messing around with IDA Pro Free, I saw that the calls to GetOpenFileNameA and GetSaveFileNameA were the same in both an unpatched SimCity 2000 and SimCity Classic executable files. In addition to the actual patch, some key information on the problem was described in a forum posting here. The patch I mentioned in a previous post loads an older File Open/Save dialog box from Windows 95 and not the newer ones that appear in Windows XP and higher (see a comparison here: old and new). It’s been a while since my last post but I want readers to know that there is now a different patch for SimCity 2000 Deluxe for Win95 out there.
