Added skeleton driver for two Kyle Hodgetts games, Virtual Combat and Shadow Fighters. Each running on the same hardware.

Browse Source 
Each game has 2 68000's, and one unemulated Intel i860XR CPU.  I couldn't find docs for the i860 anywhere!
Virtual Combat is a stereoscopic game using an additional i860 to drive the second eye.
The ROMs all seem to check out as valid, with human-readable strings throughout.
The sound program is extremely simple for each, and the sound data ROMs are simply Creative Labs VOC files concatenated to eachother.
A MC6845P lives by the edge connector.

Additional notes in the driver.

Roms uploaded to /roms/current/v & /roms/current/s.

Wiki updated with skeleton driver status.

/*
Virtual Combat hardware games.
----
There are two known games on this hardware. Both are developed by
Kyle Hodgetts.
Virtual Combat (c) VR8 Inc. 1993
http://arcade.sonzogni.com/VRCombat/
Shadow Fighters (German) (c) Sega? 1989?
----
There are two boards to this hardware. The upper, which contains the
graphics ROMs and the i860, and the lower which contains the main
and sound CPU's. Virtual Combat sports two upper boards which presumably
output a different rasterization of the scene for each stereo eye.
UPPER:
Intel I860 XR processor
MB8298-25P-SK RAMS x12 (silkscreen said 62256)
Analog device ADV476KN50E (silkscreen said BT476)
20 MHZ Oscillator
8-way DIP switch
574200D x4
PAL palce24v10 x2 (next to the i860)
LOWER:
Motorola MC68000P12 x2
12 MHz Oscillator x2
Harris ADC0804LCN x2
4 MB8298-25P-SK RAMS (in groups of 2 off by themselves)
1 CXK58257SP-10L at each end of the SNDCPU ROMS and the CPU ROMS (4 chips total)
Motorola MC6845P CRT controller
2x 27C010A containing sound code
Xx 27C040 containing sound data (VOC files)
Dallas DS1220Y - closest to pin 64 of CPU - read as a 2716 - (silkscreened "6116")
Xx 27c040 containing program code, etc.
----
NOTES : Shadow Fighters appears to have been dumped from an earlier
revision of the hardware. There are no IC labels, and
lots of factory rework has been done to the bottom board.
Because the board was so early for Shadow Fighters, there were
no IC locations silkscreened on the PCB. The locations
from Virtual Combat have been used.
The Shadow Fighters bottom board has an extra 20 mhz xtal on it.
The data stored in REGION_SOUND1 is simply a series of
Creative Media VOC files concatenated to eachother.
The sound program (REGION_CPU2) is about 640 bytes long.
The graphics ROMs have had images successfully extracted from
them. Pictures for Shadow Fighters can be found online.
The hardware is said to run at medium resolution.
The SRAM module dump can likely be thrown away for both games.
The PAL that's dumped for Shadow Fighters looks pretty bad.
Websites seem to say Shadow Fighters is a SEGA game, but I
couldn't find a SEGA string anywhere in the ROMs. I also,
however, could not find a VR8 string in the Virtual Combat
ROMs, so who knows... Kyle's name is easily found in both
though :).
TODO : This is a skeleton driver. Nearly everything.
i860XR-25 CPU core!
