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

TODO:
- Find out how layers are enabled\disabled
- dangar input ports - parent set requires F2 be held for Service Mode
- wrong title screen in ninjemak
- bit 3 of ninjemak_gfxbank_w, there currently is a kludge to clear text RAM
  but it should really copy stuff from the extra ROM.
- Likely missing MCU emulation/simulation for displaying text layer for Ninja Emaki.
  There is no text displayed when you enter Service Mode when there should be.
  Examine $3000+ in file loaded for "gfx5".
