How to extract files from TyranoBuilder (NWJS, .exe)

[R.I.P.]

In your place I would just rip these 2D textures directly from in-game, but I don't know if a way exist for WebGL renderer (maybe OGLE ?).

Thanks. I tried GLIntercept and Apitrace but both seem to not support EGL (or OpenGL ES? Even though it's supposed to be an option in apitrace).

Also I was wrong about this being Construct2 games. It's actually TyranoBuilder (a lot of engines use NWJS these days). I updated the title and post.
