I'll take another look but doesn't the input general just configure key mappings?
No, all mappings. You might have to enable joystick (in \mame\mame.ini) to configure your joystick before going into the Tab menu tho.
I messed around in the analog controls section with sensitivity and digital speed. I'll take a better look at the input general area.
That's right, once mapped this stuff will adjust it.
I think it's like someone else said, Ikari Warriors is just hard to configure. I guess I have to wait until I have a 12 position rotary and my cab is built.
Funnily enough though, MAME's Ikari support is expecting an optical-analog input (ie mouse), rather than a digital signal as per the original game (& likewise Druin's interface). So even with a mechanical rotary joystick Ikari will not play arcade perfect, unfortunately.
That said, AnalogMAME's support might be better (I'm not sure) or as a last resort you could probably edit MAME's source...not sure if anyone has done this before (?)
