Also, if anyone encounters any issues in 3d accelerated mode, such as a flickering screen with recent Nvidia cards, they should install dgVoodoo 2. It contains both a 3dfx and D3D wrapper, but you'll only want to use the D3D wrapper. Extract DDraw.dll, D3DImm.dll, and the configuration tool to your MM8 directory, then select it as your display device in the MM8Setup tool. Works flawlessly for MM7 and 8 on Windows 7 or 8.1.
