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

MJ-8956 HW games (c) 1989 Jaleco / NMK / UPL

driver by Angelo Salese, based on early work by David Haywood
Special thanks to Uki and Yasu for the priority system explanation.

Similar to the NMK16 / Jaleco Mega System 1 boards but without sprites.

Notes(general):
-I think that the 0xf0000-0xfffff area is shared with the MCU because:
\-The first version of the MCU programs (daireika/mjzoomin) jump in that area.
  Then the MCU upload a 68k code;the programs are likely to be the same for all the games,
  for example if the program jumps to $f0020 it means a sample request.
\-Input ports located there.Program doesn't check these locations at P.O.S.T. and doesn't
  give any work ram error.
\-Additionally all the games have a MCU protection which involves various RAM areas,
  that controls mahjong panel inputs.Protection is simulated by
  adding a value to these RAM areas according to what button is pressed.

TODO:
- kakumei2: unemulated RNG;
- daireika: the ranking screen on the original pcb shows some hearts instead of the "0".
  Some investigation indicates that the game reads area "fe100" onwards for these to be filled.
  These are likely to be provided by one of the mcu snippets...
- kakumei/kakumei2: has weird text layer strings in test mode (like "#p control panel"),
  unsure if this one is somehow related to the above daireika bug, it's a BTANB or something else.
- Check if urashima has a "mode 3" for the layer 0 tilemap (doesn't seem so);
- There could be timing issues caused by MCU simulation at $80004;
- Imperfect sound banking for 1st MCU version (especially noticeable for daireika);
- suchiesp: I need a side-by-side to understand if the PAL shuffling is correct with the OKI BGM ROM.
- urashima: doesn't use the mega system 1 tilemap devices, MCU might actually be responsible
  for that too (cfr. notes).

Notes (1st MCU ver.):
- $f000e is bogus,maybe the program snippets can modify this value,or the MCU itself can
  do that,returning the contents of D0 register seems enough for now...
  Update: Improved it for the new mcu simulation,now it pulls all the values from 0x00 to
  0x0f, it seems to be a MCU call snippet for the $f0000 work ram;
- $f030e is a mirror for $f000e in urashima.
- I need more space for MCU code...that's why I've used an extra jmp when entering
  into mcu code,so we can debug the first version freely without being teased about
  memory space.
  BTW,the real HW is using a sort of bankswitch or I'm missing something?
- $f0020 is for the sound program,same for all games, for example mjzoomin hasn't any clear
  write to $80040 area and the program jumps to $f0020 when there should be a sample.
- Likewise, D0 upper byte is used, not 100% sure about its meaning (banking? voice channel control?).

============================================================================================
Debug cheats:

-(suchiesp)
*
$fe87e: bonus timer,used as a count-down.
*
$f079a: finish match now
*
During gameplay,set $f0400 to 6 then set $f07d4 to 1 to advance to next
level.
*
$f06a6-$f06c0: Your tiles
$f06c6-$f06e0: COM tiles
---- ---- --xx ----: Defines kind
---- ---- ---- xxxx: Defines number
*
$f0434: priority number
