Karian Cross     deniam-16b 1997/04/17
LOTTERY GAME     deniam-16c 1997/05/21
Logic Pro 2      deniam-16c 1997/06/20
Propose          deniam-16c 1997/06/21

They call the hardware "deniam-16", but it's actually pretty much identical to
Sega System 16.


Notes:

- The logicpr2 OKIM6295 ROM has four banks, but the game seems to only use 0 and 1.
- logicpro dip switches might be wrong (using the logicpr2 ones)
- flip screen is not supported but these games don't use it (no flip screen dip
  and no cocktail mode)
- if it's like System 16, the top bit of palette ram should be an additional bit
  for Green. But is it ever not 0?
- Logic Pro 2 sound test menu is bugged on the real pcb. You can't change the sound
  sample and music selected due to an incorrect compare/branch at pc=0x3fd0/0x3fd2
  (for sfx) and pc=0x3ffa/0x3ffc (for bgm). Patching the two compare opcodes with
  the value 0xb041 lets you properly change the sound and bgm in the test mode,
  otherwise they're stuck at 19 and 03 respectively. Verified on real hardware.
- Logic Pro has an unemulated graphical effect: when you insert a coin, the screen
  becomes very slightly darker until the next 'scene change'. This is not emulated
  yet.
- Both Logic Pro and Logic Pro 2 have 4 pixels of garbage (related to fg layer?)
  at the left edge of the screen on the real pcb. Sprites can properly be displayed
  in this area. Mame displays this area as black.
