The one thing I have noticed with a lot of his is that where he didn't do a specific texture bmp for the interior or some basic parts of the aircraft, those areas turn black in Accel and after a lot of checking, it became apparent that there was no way to correct that unless you could get the original source code (which he does not allow).
As a general rule, every one that I've used in FSX in the past worked very well in SP2/Accel, with that one exception.
