Hello folks,

bought the game from GOG.com to look into it...

It seems the game doesn't query further IDxDiag properties sequentially if a
property doesn't exist, leading to later error about "unknown <foo>".

Even with +dxdiag,+devenum trace log you can't really spot it until you debug
the actual game ;-)

Prerequisite: 'winetricks -q dotnet35sp1' in clean 32-bit WINEPREFIX

The game queries the following properties from Wine's dxdiagn in sequential
order:

--- snip ---
"szDeviceName"
"szDescription"
"szKeyDeviceID"
"szKeyDeviceKey"
"szManufacturer"
"szChipType"
"szDACType"
"szRevision"
"szDisplayMemoryLocalized"
"szDisplayMemoryEnglish"
"szDisplayModeLocalized"
"szDisplayModeEnglish"
"dwWidth"
"dwHeight"
"dwBpp"
"dwRefreshRate"
"szMonitorName"
"szMonitorMaxRes"
"szDriverName"
"szDriverVersion"
"szDriverAttributes"
"szDriverLanguageEnglish"
"szDriverLanguageLocalized"
"szDriverDateEnglish"
"szDriverDateLocalized"
"lDriverSize"
"szMiniVdd"
"szMiniVddDateLocalized"
"szMiniVddDateEnglish"
"lMiniVddSize"
"szVdd"
"bCanRenderWindow"
"bDriverBeta"
"bDriverDebug"
"bDriverSigned"
"bDriverSignedValid"
"szDeviceIdentifier"
"szDriverSignDate"
"dwDDIVersion"
"szDDIVersionEnglish"
"szDDIVersionLocalized"
"iAdapter"
"szVendorId"
"szDeviceId"
"szSubSysId"
"szRevisionId"
"dwWHQLLevel"
"bNoHardware"
"bDDAccelerationEnabled"
"b3DAccelerationExists"
"b3DAccelerationEnabled"
"bAGPEnabled"
"bAGPExists"
"bAGPExistenceValid"
"szDXVAModes"
"szDDStatusLocalized"
"szDDStatusEnglish"
"szD3DStatusLocalized"
"szD3DStatusEnglish"
"szAGPStatusLocalized"
"szAGPStatusEnglish"
"szNotesLocalized"
"szNotesEnglish"
"szRegHelpText"
"szTestResultDDLocalized"
"szTestResultDDEnglish"
"szTestResultD3D7Localized"
"szTestResultD3D7English"
"szTestResultD3D8Localized"
"szTestResultD3D8English"
"szTestResultD3D9Localized"
"szTestResultD3D9English"
--- snip ---

Due to first missing property "szChipType", the video ram
"szDisplayMemoryLocalized" is never queried for.

I think you should provide at least all missing properties until all important
ones are queried (in order).
They have to exist, even if the values are not really matching the hardware.
Though the last ones doesn't seem to be very useful at all and can be left out
(values are not evaluated).

Regards
