Hey people. What you want to do is this:
1. Install Wine 1.6. (1.7 may work, but Wine's website says it's a good idea not to try) Installation varies by distro, so figure that part out yourself.
2. Now look for an app called Notepad. Open it - it's the Wine Notepad. Running it will initialize Wine into your home folder.
3. Open the app called Winetricks. Choose the option "Select the default wineprefix", press OK, then choose "Install a Windows DLL or component", then press OK again.
4. In the menu that comes, choose all this:
- d3dx9
- d3dx9_26
- d3dx9_28
- d3dx9_31
- d3dx9_35
- d3dx9_36
- d3dx9_39
- d3dx9_42
- d3dx9_43
- d3dxof
- devenum
- dinput8
- directmusic
- directplay
- dmsynth
- dsdmo
- dsound
- dxdiag
- dxdiagn
- quartz
Press OK. The required stuff will be downloaded and installed.
5. Put a copy of MM2 anywhere in ~/.wine/drive_c/ - this is the C:\ drive of Wine. (If you don't know where this is, just type it in your file manager's address bar)
And now right-click the Midtown2.exe and open it with Wine. It'll work.
