Just replace the dosbox.exe in a GOG game folder with this one. Also make sure to set in the DOSBox config file for every game these parameters:

fullresolution=desktop

output=openglnb

aspect=false

scaler=normal3x

autofit=false

Note that you shouldn't copy the config file provided with DOSBox CRT, as every DOS game on GOG comes with its own optimized config file. You just need to change some of the lines.

Does it have a similar CRT shader, though?

I absolutely love DOSBox-CRT and use it with every DOS game I have on GOG. But one of them, PowerSlave that is, isn't working properly. Namely, the music doesn't work, although it works fine with the bundled DOSBox. Any idea what's causing this? I think I've tried everything.
