+
+ Sega System C (System 14)/C2 Driver
+ driver by David Haywood and Aaron Giles
+ ---------------------------------------
+ Last Update 15 Nov 2005
+
+
+ Sega's C2 was used between 1989 and 1994, the hardware being very similar to that
+ used by the Sega MegaDrive/Genesis Home Console Sega produced around the same time.
+
+ The Columns and Bloxeed (USA) manual call this system 'System 14' instead of system C/C2.
+
+
+ todo: fill in protection chip data

+
+ Notes:
+ Bloxeed doesn't Read from the Protection Chip at all; all of the other games do.
+ Currently the protection chip is mostly understood, and needs a table of 256
+ 4-bit values for each game. In all cases except for Poto Poto and Puyo Puyo 2,
+ the table is embedded in the code. Workarounds for the other 2 cases are
+ provided.
+
+ I'm assuming System-C was the Board without the uPD7759 chip and System-C2 was the
+ version of the board with it, this could be completely wrong but it doesn't really
+ matter anyway.
+
+ Bugs: Puyo Puyo ends up with a black screen after doing memory tests
+ Battery-backed RAM needs to be figured out
+
+ Thanks: (in no particular order) to any MameDev that helped me out .. (OG, Mish etc.)
+ Charles MacDonald for his C2Emu .. without it working out what were bugs in my code
+ and issues due to protection would have probably killed the driver long ago :p
+ Razoola & Antiriad .. for helping teach me some 68k ASM needed to work out just why
+ the games were crashing :)
+ Sega for producing some Fantastic Games...
+ and anyone else who knows they've contributed :)

+ Palette Tables
+*******************************************************************************
+
+ Both the background and sprites within the VDP have 4 possible palettes
+ to select from. External hardware on the C2 boards, controlled by the
+ EPM5032 chip and the I/O chip, allows for more complex palette selection.
+ The actual palette entry comes from:
+
+ Bits 10-9 = output from I/O port H
+ Bits 8-5 = output from EPM5032
+ Bits 4-0 = direct from the VDP
+
+ In order to compute bits 8-5, the EPM5032 gets the sprite/background
+ output line along with the two bits of palette info. For most games, the
+ two bits of palette info map straight through as follows:
+
+ Bits 10-9 = output from I/O port H
+ Bits 8 = sprite/background select
+ Bits 7-6 = palette selected by writing to prot_w
+ Bits 5-4 = direct from the VDP palette select
+ Bits 3-0 = direct from the VDP
+
+ However, because there are 4 bits completely controlled by the EPM5032,
+ it doesn't have to always map this way. An alternate palette mode can
+ be selected which alters the output palette by swizzling the color
+ RAM address bits.

+ Input Ports
+*******************************************************************************
+
+ The input ports on the C2 games always consist of 1 Coin Port, 2 Player
+ Input ports and 2 Dipswitch Ports, 1 of those Dipswitch Ports being used
+ for coinage, the other for Game Options.
+
+ Most of the Games List the Dipswitchs and Inputs in the Test Menus, adding
+ them is just a tedious task. I think Columnns & Bloxeed are Exceptions
+ and will need their Dipswitches working out by observation. The Coin Part
+ of the DSW's seems fairly common to all games.

+All of the Sega C/C2 games apart from Bloxeed used a protection chip.
+The games contain various checks which make sure this protection chip is
+present and returning the expected values. It appears that different
+tables are used for Japanese vs. English variants of some games
+(Puzzle & Action 2) but not others (Columns).
+
+
+The basic operation in the EPM5032 macrocell (that is, without using the expander
+products) is:
+
+out = x1 XOR (x2 OR x3 OR x4)
+
+where x1, x2, x3, and x4 are the AND of any number of input bits. Each input can
+be inverted. The inputs come either from the external pins or from feedback from
+the output pins.
+
+Expander products (64 in total) are the NOT of the AND of any number of input bits
+(optionally inverted). It's not clear whether the I/O feedback is available to
+the expander or not. Looking at bit 1 of prot_func_tfrceac(), it would seem that
+it should be, otherwise I don't see how the formula could be computed.
