That's where I noticed the problem in the first place. Trying to map a control to a joystick shows the joystick as joystick 2. I could if I wanted map every single control on every single game, but that's a lot of mapping.

Ah, I see where they are now. Is there a make target to install them or should I just copy them manually?

If I turn off switchres the problem does not happen, but I need to try switchres to see if I can get a speedup to 100%, since the game I tried (Twinbee) is 100% in a small window, but is less than 100% in a larger window and in full screen.

My resolution is 1920x1090. Twinbee is 224x256. 4X is less than my output resolution.

What does it do then? I thought that it was for the case where the real machine doesn't produce square pixels. Wouldn't using it end up displaying every game correctly, by definition?

Edit (2): Doing some experimentation, it seems the pixel aspect on produces 1:1 pixels and pixel aspect off doesn't. So that explains why it won't do prescale 4. If I have pixel aspect on and nounevenstretch it produces 224x256 and stretches by a factor of exactly 4.

In windowed mode, I do also see a problem where the window is too tall, whether pixel aspect is on or not and whether unevenstretch is on or not, although the amount by which it is too tall varies depending on those settings. How can I prevent this?
