ShaderGlass test with PCSX2 - CRT simulation on Windows
4 games tested with the ShaderGlass app. It emulates the CRT pretty well and has tons of presets and settings to tinker with. It's now my preferred way to play retro games. Sadly the YT compression doesn't show how good it is.
There is the window cloning mode (seen in this video) and the "glass" mode where the window gets transparent and whatever is behind it gets the CRT effect (and you can click on things behind it). There is also a fullscreen mode if you want that, I guess.
Oh, and the app is free.
