Question for owners of WinXP-based MAME cabs:
What's the control setup on these, and are there any additional requirements (screen resolution, etc)?
I'd like to make this playable on them (well, ones with recent hardware anyway).
Also, current state:

Still no enemies other than the placeholder, however it has now multiple attack and movement patterns.
I'm also thinking about replacing the circuit background with something more interesting.
Either random boxes with glowing edges (should look like some kind of virtual city), or some kind of angular techno-foliage (like Vectrex trying to display Crysis jungle

), or both.
Any other ideas (something simple please)?
