ToDo: (in order or priority?)

Street Fighter 3 2nd Impact uses flipped tilemaps during flashing, emulate this.

Figure out proper IRQ10 generation:
 If we generate on DMA operations only then Warzard is OK, otherwise it hangs during attract
 HOWEVER, SFIII2 sometimes has messed up character profiles unless we also generate it periodicly.
 I think the corrupt background on some of the lighning effects may be realted to this + the DMA
 status flags.

Alpha Blending Effects
    These are actually palette manipulation effects, not true blending.  How the values are used is
    not currently 100% understood.  They are incorrect if you use player 2 in Warzard

Linezoom
    Is it used anywhere??

Palette DMA effects
    Verify them, they might not be 100% accurate at the moment

Verify Full Screen Zoom on real hardware
 Which is which, x & y registers, how far can it zoom etc.

Verify CRT registers
 Only SFIII2 changes them, for widescreen mode.  What other modes are possible?

Sprite positioning glitches
 Some sprites are still in the wrong places, seems the placement of zooming sprites is imperfect
 eg. warzard intro + cutscenes leave the left most 16 pixels uncovered because the sprite is positioned incorrectly,
     the same occurs in the sf games.  doesn't look like the origin is correct when zooming in all cases.

Gaps in Sprite Zooming
 probably cause by use of drawgfx instead of processing as a single large sprite, but could also be due to the
 positioning of each part of the sprite.  Warzard is confirmed to have gaps during some cutscenes on real hardware.

Capcom CP SYSTEM III Hardware Overview
Capcom, 1996-1999

From late 1996 to 1999 Capcom developed another hardware platform to rival the CPS2 System and called
it CP SYSTEM III. Only 6 games were produced....

** NOT DUMPED but known to exist

The Game Region / No CD Flags / Development flags etc. are controlled by a byte in the bios roms.  The CDs
contain revisions of the game code and are independant of the region.

The CP SYSTEM III comprises a main board with several custom ASICs, custom 72-pin SIMMs for program
and graphics storage (the same SIMMs are also used in some CPS2 titles), SCSI CDROM and CDROM disc,
and a plug-in security cart containing a boot ROM, an NVRAM and another custom ASIC containing vital
decryption information held by a [suicide] battery.

Not much is known about the actual CPU used in this system due to the extensive use of encryption,
and the volatile nature of the security information. There appears to be a custom Hitachi SH-2
CPU on the mainboard and there has been confirmed to be one in the cart. Tests were done by decrypting
the BIOS and code and running it on the PCB. It is known that neither of these CPU's will run standard
(i.e. unencrypted) SH2 code.

The security cart is thought to work like this....  the flashROM in the cart contains a program BIOS which is
decrypted by the CPU in the cart (the CPU has built-in decryption) then executed by that CPU to boot the BIOS
code.  Even though the code in the flashROM is encrypted, the cart can run it even if it is dead/suicided because
it has been discovered that the BIOS contains a hidden security menu allowing the cart to be loaded with the
security data. This proves the cart runs the BIOS even if it is dead. The special security menu is not
normally available but is likely accessed with a special key/button combination which is unknown ATM.
The cart contains a FM1208S NVRAM which appears to either be unused or holds game settings. Because the CPU
in the cart is always powered by a battery, it has stealth capability that allows it to continually monitor
the situation. If the custom CPU detects any tampering (generally things such as voltage fluctuation or
voltage dropping or even removal of the cart with the power on), it immediately erases the SRAM inside the
CPU (and thus the key) which effectively kills the security cart dead. This also suggests that the custom
Capcom CPU contains some additional internal code to initiate the boot process which is battery-backed
as well. It is known (from decapping it) that the CPU in the security cart does contain an amount of static
RAM for data storage and a SH2 core.

The main board uses the familiar Capcom SIMM modules to hold the data from the CDROM so that the life of
the CD drive is maximized. The SIMMs don't contain RAM, but instead TSOP48 surface mounted flashROMs
that can be updated with different games on bootup using a built-in software updating system.
The SIMMs that hold the program code are located in positions 1 & 2 and are 64MBit.
The SIMMs that hold the graphics are located in positions 3, 4, 5, 6 & 7 and are 128MBit.
The data in the SIMMs is not decrypted, it is merely taken directly from the CDROM and shuffled slightly
then programmed to the flashROMs. The SIMMs hold the entire contents of the CDROM.

To swap games requires the security cart for the game, it's CDROM disc and the correctly populated type
and number of SIMMs on the main board.
On first power-up after switching the cart and CD, you're presented with a screen asking if you want to
re-program the SIMMs with the new game. Pressing player 1 button 2 cancels it. Pressing player 1 button 1
allows it to proceed whereby you wait about 25 minutes then the game boots up almost immediately. On
subsequent power-ups, the game boots immediately.
If the CDROM is not present in the drive on a normal bootup, a message tells you to insert the CDROM.
Then you press button 1 to continue and the game boots immediately.
Note that not all of the SIMMs are populated on the PCB for each game. Some games have more, some less,
depending on game requirements, so flash times can vary per game. See the table below for details.

                                                           No game uses a SIMM at 7
                                                           See main board diagram below for SIMM locations.

Due to the built-in upgradability of the hardware, and the higher frame-rates the hardware seems to have,
it appears Capcom had big plans for this system and possibly intended to create many games on it, as they
did with CPS2. Unfortunately for Capcom, CP SYSTEM III was an absolute flop in the arcades so those plans
were cancelled. Possible reasons include...
- The games were essentially just 2D, and already there were many 3D games coming out onto the market that
  interested operators more than this.
- The cost of the system was quite expensive when compared to other games on the market.
- It is rumoured that the system was difficult to program for developers.
- These PCBs were not popular with operators because the security carts are extremely static-sensitive and most
  of them failed due to the decryption information being zapped by simple handling of the PCBs or by touching
  the security cart edge connector underneath the PCB while the security cart was plugged in, or by power
  fluctuations while flashing the SIMMs. You will know if your cart has been zapped because on bootup, you get
  a screen full of garbage coloured pixels instead of the game booting up, or just a black or single-coloured
  screen. You should also not touch the inside of the security cart because it will be immediately zapped
  when you touch it! The PCB can detect the presence of the security cart and if it is removed on a working game,
  the game will freeze immediately and it will also erase the security cart battery-backed data.
