my bad, I only ever played it once or twice on an emu. I knew there were two sticks, and I must have assumed there was a fire button.

Relatively easy on an arcade stick but might be impractical on a touch screen or controller.

controller could be a little tricky, a similar movement was a macro for katamari damacy, but it's doable.

on a touchscreen, yeah, forget it, I wouldn't even want to try...
