/*******************************************************************************
Skeleton driver for "PlayCenter" PC-based touch games
Hardware overview for "PlayCenter Champions Tournament":
Motherboard: EPoX EP-MVP4F
Unknown RAM size, AMD K6 processor (unknown speed)
PCI Ethernet card (unknown chipset)
The security scheme is quite simple:
Each minigame is a VisualBasic executable that receives three numbers when
invoked, the hard disk serial number (readed through the Windows enumerator
file), the Ethernet MAC address, and a third one, and concatenates them
moving some bits around.
Then, calls the security board via RS-232 (it's a simple PCB with a PIC and
a serial port), getting another number (the PIC always returns the same
number, there are no states or logic).
Finally, the game compares both numbers with a simple formula, refusing to
work if there's a mismatch.
Since the security involves hardware unique serial numbers, each PIC program
is unique for each single machine (and these hardware parts are not
replaceble by the user / operator).
