If you want to fly the original approach of VHHX, you can go to the Vatsim Hong Kong Division. All charts and approach procedures are available for free download. And sometimes, if you fly online in network, you can also have ATC for this airport.
Try to do this with captainsim T7. My opinion, it should be possible to fly the approach with CS T7 without AP. The approach is flown by a Localizer DME approach. LLZ/DME Approach. No Glideslope! Or you can fly a VOR/DME Approach or NDB Approach. The glidepath was 3.1°.
The approach chart show, not much corrections needed, only fly to the checkerboard Heading 45° and turn right. All charts can be found at Vatsim Hong Kong.
Can not send a link in this post, just google for Vatsim Hong Kong and you will find it.
Have fun :)

Your approach is flown wrong. You do not fly to the checkerboard, your course is to much left. The hill you see on left of your picture is the hill with the checkerboard. So coming from Kowloon you must fly a heading 45° to the checkerboard and then make a right turn before the hill down to the runway. So the turn ist much more difficult and short. The way you fly the turn on your pictures would not be legal in real world because you are to low and the distance between your left wing and the hill is to close.
