How do I disable the Y-axis for the mouse?
I've finally learned how to remap the keys in DOSBox so now I can play with the WASD, although it is a bit different, since we have to push alt in order to actually strafe.

Not necessarily. You can use DOSBox to remap the A and D keys to activate ALT and the left/right cursor key so that they act as strafe left/right. You cannot circle strafe, though, as mouse left and right when pressing the A and D keys also then causes strafing, so that is a limitation in what we can do in the old Wolf3D engine.

I'm looking forward to the day that we finally get an ECBlake so that we can play the Blake Stone games with mouselook and WASD, as well as the higher resolutions. ECWolf works quite nicely for the Wolfenstein games, but ECBlake isn't ready yet.

Back then I didn't know this. Now I sure do. :)

Yeah, can't wait for ECBlake...
