Dragon Quest X online - Problems with Displaydepth.fx

Been trying to get Displaydepth to work properly with this game, it does work with DG Voodoo (DX11), but under the default DX9 version, it does not work, tried many different variations.

Also, Mass Effect series, both DX9 and the legendary series also had the same problem, but with those games, it can easily be fixed if I added this:

Either within the ReShadePresent.ini or the actual profile .ini itself, I adjusted the Displaydepth.fx:

[DisplayDepth.fx]
Advanced_help=0
bUIShowOffset=0
bUIUseLivePreview=1
Depth_help=0
fUIDepthMultiplier=1.000000
fUIFarPlane=1000.000000
fUIScale=1.000000,1.000000
iUILogarithmic=0
iUIOffset=0,0
iUIPresentType=2
iUIReversed=0
iUIUpsideDown=0

Works perfectly, I tried this with Dragon Quest X online (DX9), it does not work.

Also, with DG Voodoo (DX11) with this game, I would need to use both: Copy depth buffer before clear operations & Copy depth buffer before fullscreen draw calls, works great, but under the default DX9, it does not work, tried also under: Displaydepth.fx: Under: Edit global preprocessor defintions, 3rd parameter down: Reshade_depth_input_is, tried both 0 and 1 as normally I only have to change this particular line, again, doesn't work.

Just heads up in regards about this game (DX9) with reshade.

I tried the newest version of reshade, as well as some of the very old ones, (V. 4+), I am still getting the error within the addon tab: No clear operations were found with the selected buffer, and so on.

Tried different ways to get it to work, it does not work properly.

It seems this is the only DX9 game, combined with reshade, displaydepth.fx doesn't work with a darn, all the other games works perfectly.

Any workaround is much greatly appreciated.

EDIT:

While using version 4.9.1:

Within the d3d9.log, there was several errors, all pertaining to depth buffer, here is one specific line says:

Failed to retrieve texture from depth surface! HRESULT is E_NOINTERFACE.
