     3: 	Sega System C/C2 Driver
     4: 	driver by David Haywood and Aaron Giles
     5: 	---------------------------------------
     6: 	Version 0.54 - 02 Feb 2003
     7: 
     8: 	Latest Changes :
     9: 	-----+-------------------------------------------------------------------------------------
    10: 	0.71 | Started adding Support for Megatech, first step is improving the Genesis Emulation
    11: 		 | The rendering will also need improving to support mid-frame palette changes
    12: 		 | (RGB_DIRECT) maybe use tilemaps if its not too messy, added Genesis sound based on
    13: 		 | Mess code
    14: 	0.54 | Added Ribbit! support. Recoded some of the VDP to handle vertical windows. Removed
    15: 	     | the bitmap cache and added partial updating support.
    16: 	0.53 | Set the Protection Read / Write buffers to be cleared at reset in init_machine, this
    17: 		 | fixes a problem with columns when you reset it and then attempted to play.
    18: 		 |  (only drivers/segac2.c was changed)
    19: 	0.52 | Added basic save state support .. not too sure how well it will work (seems to be
    20: 		 | ok apart from sound where i guess the sound core needs updating) size of states
    21: 		 | could probably be cut down a bit with an init variables from vdp registers function
    22: 	0.51 | Added some Puyo Puyo (English Lang) Bootleg set, we don't have an *original* english
    23: 		 | set yet however.  Also added a 2nd Bootleg of Tant-R, this one still has protection
    24: 		 | inplace, however the apparently board lacks the sample playing hardware.
    25: 		 | Removed 'Button3' from Puyo Puyo 2, its unneeded, the Rannyu Button is actually the
    26: 		 | player 1 start button, its used for stopping a 2nd player interupting play.
    27: 	0.50 | Added some Columns/Puyo Puyo 2 dips from Gerardo. Fixed nasty crash bug for games
    28: 		 | not using the UPD7759. Made some minor tweaks to the VDP register accesses. Added
    29: 		 | counter/timer description. Attempted to hook up battery RAM.
    30: 	0.49 | Fixed clock speeds on sound chips and CPU. Tweaked the highlight color a bit.
    31: 	0.48 | Added a kludge to make Stack Columns high score work. Fixed several video-related
    32: 		 | differences from c2emu which caused problems in Puyo Puyo.
    33: 	0.47 | Fixed Thunder Force hanging problem. No longer calling the UPD7759 on the C-system
    34: 		 | games.
    35:     0.46 | Cleaned up the Dip Switches. Added Ichidant and Puyopuy2 Dips.
    36:          | Todo: Complete Columns and Bloxeedc Dips.
    37: 	0.45 | Fixed interrupt timing to match c2emu, which fixes scroll effects in several games.
    38: 		 | Swapped sample ROM loading in some bootlegs. Added support for screen disable.
    39: 	0.44 | Major cleanup. Figured out general protection mechanism. Added INT 4 and INT 2
    40: 		 | support. Added shadow effects. Hooked up sound chips. Fixed palette banking. ASG
    41: 	0.43 | Added Support for an English Language version of Ichidant-R (and I didn't even think
    42: 		 | it was released outside of Japan, this is a nice Turn-Up) .. I wonder if Tant-R was
    43: 		 | also released in English ...
    44: 	0.42 | Removed WRITE_WORD which was being used to patch the roms as it is now obsolete,
    45: 		 | replaced it with mem16[addy >> 1] = 0xXXXX which is the newer way of doing things.
    46: 	0.41 | Mapped more Dipswitches and the odd minor fix.
    47: 	0.40 | Updated the Driver so it 'works' with the new memory system introduced in 0.37b8
    48: 		 | I'm pretty sure I've not done this right in places (for example writes to VRAM
    49: 		 | should probably use data16_t or something.  <request>Help</request> :)
    50: 		 | Also Added dipswitches to a few more of the games (Borench & PotoPoto) zzzz.
    51: 	0.38 | Started Mapping Dipswitches & Controls on a Per Game basis.  Thunderforce AC now has
    52: 		 | this information correct.
    53: 	0.37 | Set it to Clear Video Memory in vh_start, this stops the corrupt tile in Puyo Puyo 2
    54: 		 | however the game isn't really playable past the first level anyhow due to protection
    55: 	0.36 | Mainly a tidy-up release, trying to make the thing more readable :)
    56: 		 | also very minor fixes & changes
    57: 	0.35 | Added Window Emualtion, Horizontal Screen Splitting only (none of the C2 Games
    58: 		 | split the screen Vertically AFAIK so that element of the Genesis Hardware doesn't
    59: 		 | need to be emulated here.
    60: 		 | Thunderforce AC (bootleg)  tfrceacb is now playable and the test screens in Potopoto
    61: 		 | will display correctly.  Don't think I broke anything but knowing me :)
    62: 	0.34 | Fixed Some Things I accidentally broke (well forgot to put back) for the
    63: 		 | previous version ...
    64: 	0.33 | Fixed the Driver to Work in Pure Dos Mode (misunderstanding of the way MAME
    65: 		 | allocated (or in this case didn't allocate) the Palette Ram.
    66: 		 | Fixed a minor bug which was causing some problems in the scrolling in
    67: 		 | potopoto's conveyer belt.
    68: 	0.32 | Added Sprite Flipping This improves the GFX in several games, Tant-R (bootleg)
    69: 		 | is probably now playable just with bad colours on the status bar due to missing
    70: 		 | IRQ 4 Emulation.  Sprite Priority Also fixed .. another Typo
    71: 	0.31 | Fixed Several Stupid Typo Type Bugs :p
    72: 	-----+-------------------------------------------------------------------------------------

    74: 	Sega's C2 was used between 1989 and 1994, the hardware being very similar to that

    92: 
    93: 
    94: 	Notes:	Eng indicates game is in the English Language, Most Likely a European / US Romset
    95: 			Jpn indicates the game plays in Japanese and is therefore likely a Japanes Romset
    96: 
    97: 			Another way to play these games is with Charles Macdonald's C2Emu, which was the
    98: 			inspiration for much of this code. Visit http://cgfm2.emuviews.com for the
    99: 			download, also home of some _very_ good Sega Genesis VDP documentation.
   100: 
   101: 			The ASM 68k Core causes a scoring problem in Columns, Starscream does this also,
   102: 			with the C 68k Core the scoring in columns is correct.
   103: 
   104: 			Bloxeed doesn't Read from the Protection Chip at all; all of the other games do.
   105: 			Currently the protection chip is mostly understood, and needs a table of 256
   106: 			4-bit values for each game. In all cases except for Poto Poto and Puyo Puyo 2,
   107: 			the table is embedded in the code. Workarounds for the other 2 cases are
   108: 			provided.
   109: 
   110: 			I'm assuming System-C was the Board without the uPD7759 chip and System-C2 was the
   111: 			version of the board with it, this could be completely wrong but it doesn't really
   112: 			matter anyway.
   113: 
   114: 			Vertical 2 Cell Based Scrolling won't be 100% accurate on a line that uses a Line
   115: 			Scroll value which isn't divisible by 8.. I've never seen a C2 game do this tho.
   116: 
   117: 
   118: 	Bugs:	Puyo Puyo ends up with a black screen after doing memory tests
   119: 			Battery-backed RAM needs to be figured out
   120: 
   121: 
   122: 	Thanks:	(in no particular order) to any MameDev that helped me out .. (OG, Mish etc.)
   123: 			Charles MacDonald for his C2Emu .. without it working out what were bugs in my code
   124: 				and issues due to protection would have probably killed the driver long ago :p
   125: 			Razoola & Antiriad .. for helping teach me some 68k ASM needed to work out just why
   126: 				the games were crashing :)
   127: 			Sega for producing some Fantastic Games...
   128: 			and anyone else who knows they've contributed :)
