The play field itself is already taller than 240 pixels and even though there are X modes that allow you to go beyond 240 scan lines, none of them work consistently on newer LCD panels. Ideally I use 360 x 270 which gives me square pixels and everything fits perfectly but it will only work in DOSBox for most people these days. I'd like people to run this on real hardware... Technically I could tilt the screen, as they did in the arcade (i.e. 240x320) but who can tilt their 4:3 LCD panel? I just happen to have one but... I think I have to use some form of panning...
