You reminded me something.
Now that I think about it.
Running UltraHLE using glideal 1.6 on TNT2, the Lens of Truth is working at some places (showing the hidden moving platform in the Shadow Temple) while not on others (unable to remove fake walls in that temple, or the screen just goes completely dark), so I can't be sure what's wrong, some screenshots will be really nice though :colgate: .
