/*******************************************************************************
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?
