+/*******************************************************************************
+ Shadow Force (c)1993 Technos
+ Preliminary Driver by David Haywood
+ Based on the Various Other Technos Games
+********************************************************************************
+
+Stephh's notes :
+
+ - As for some other M68000 Technos games (or games running on similar hardware
+ such as 'mugsmash'), the Inputs and the Dip Switches are mangled, so you need
+ a specific read handler so end-uers can see them in a "standard" order.
+ IMO you should set the USE_SHADFRCE_FAKE_INPUT_PORTS macro to 1.
+ - Why do "Coin 2" and "Service 1" buttons only work in "test mode" ?
+
+ To Do:
+
+ Graphic Glitches
+ Spurious sprite at the top right of the title screen. Visible area too large?
+ Other Interrupt?
