Hi,

Every Wine release more and more programs start to work on Wine. A
      
serious
    
problem is that not all programs can work out of the box. Some games for
instance need the windows version to be set to Windows 95 or it will
      
crash.
    
Other games like Medal of Honour need their OpenGL extension string
      
trimmed
    
to get it to work on cards which support a lot of OpenGL extensions.
      
There
    
are dozens of more examples like that.
      
The majority of Wine's options are settable via the registry and can be
given 
app-specific overrides. So how about wineprefixcreate creates registry 
entries for specific apps that are known to need special settings?

Just need to be really really careful that an app needs the change, and
that 
it's not due to a bug in Wine or something.
    

Yep wineprefixcreate should handle this and I think in combination with winecfg. One issue that I see is that an executable name is not unique. In case of games if multiple ones are using 'game.exe'  then there is a problem. For AppDefaults you can type the whole path but you don't know that in advance.

I fear that for executable some sort of md5sum needs to be stored (there might be something like that already in the app in the form  of a product code or so) for purposes like this. We should check how microsoft handles this. Anyway I think that support in the wine loader is needed.

I agree on the checksum. There could be multiple versions of the same program, even, as with Steam's case.
How would the registry fix work with wineprefixcreate? Would the user checksum the target program, and then pass as an argument to wineprefixcreate? I think it would be best to have a GUI element using winecfg, to tell the user if there are fixes to be applied.
