/***************************************************************************

"Mitchell hardware". Actually used mostly by Capcom.

All games run on the same hardware except mgakuen, which runs on an
earlier version, without RAM banking, not encrypted (standard Z80)
and without EEPROM.

Other games that might run on this hardware:
"Chi-toitsu"(YUGA 1988)-Another version of"Mahjong Gakuen"
"MIRAGE -Youjyu mahjong den-"(MITCHELL 1994)

Notes:
- Super Pang has a protection which involves copying code stored in the
  EEPROM to RAM and execute it from there. The first time the game is run,
  you have to keep the player 1 start button pressed until the title screen
  appears. This forces the game to initialize the EEPROM, otherwise it will
  not work.
  This is simulated with a kluge in input_r.
  This doesn't work with spangj! The data written to EEPROM is wrong. This is
  currently fixed by patching the ROM data so the EEPROM is right. It would be
  better to just preload the correct EEPROM, without needing the input_r kludge.

TODO:
- understand what bits 0 and 3 of input port 0x05 are
- ball speed is erratic in Block Block. It was not like this at one point.
  This is probably related to interrupts and maybe to the above bits.

 Monsters World (c)1994 TCH

 Monsters World is basically a bootleg of Mitchell's Super Pang

 The code is a patched version of the current parent 'spang' set supported by
 MAME with many code changes and the majority of strings patched out.

 Super Pang is encrypted using the 'Kabuki' encryption system, so to decrypt
 the game decrypted code and decrypted data must be split.

 Monster World contains banks of decrypted data and decrypted code scrambled
 together in a single rom, using a GAL to decode the addresses on the actual
 PCB.

 There are several other changes from Super Pang too.  Monsters World has no
 NVRAM / EEPROM, and has its own sound CPU driving only an OKI6925.  Video
 RAM Banking has also been changed.

 The actual Monsters World PCB is very close to the Speed Spin PCB but in terms
 of emulation the video etc. is closer to mitchell.c
