Hi
Can you clarify or explain how you got the chamber of secrets working with the LegacyD3DResolutionHack? My friend and I are both unable to get it working, we can't find much information in general about how to use the hack but have tried both putting the 2 DLL's in the game's system directory where the EXE is as well as overwriting the similarly named DLL's in System32 (which kept getting reverted due to security settings, but probably won't work since the D3DResolutionHack DLL files are proxy libraries I think?)
When I install Harry Potter it doesn't create any d3dim or d3dim700.dll files implying it uses System32 dlls
