The reason why they are difficult is that the old version does not have the patches or fixes like on later revisions also all the sounds don't really sync up very well unless you're running it on Windows XP. On newer versions, they fixed all the Issues and Syncs up for Windows 7 or better so the wheelies and controls, in general, are optimized on those newer versions because the OS has been changed after 2.09 to Windows 7 Embedded so the Audio Sync, and Analog Controls are very responsive due to optimization speed for newer D3D APIs. It was always like this for all D3D8 Games after Windows 7 got released.
