/* tmmjprd.c

 - split from rabbit.c  (it uses the same GFX chip, but is otherwise a different PCB, and until the methods
   of configuring the graphic chip are understood it's easier to work on them here)

 - in 16x16 tile mode, the offset into tileram doesn't neccessarily align to 16x16 tiles!  This makes using the
   tilemap system excessively difficult, as it expects predecoded tiles which simply isn't possible here.
   This is used for the girls in the intro at least, they specify 16x16 tiles on non 16x16 boundaries.
   (basically the physical tile rom addressing doesn't change between modes even if the data type does)
   (handling this in the tilemap system is very messy, might just be best with custom renderer)

 - Rom Test not hooked up (can read the gfx roms via a BANK
    - should hook this up as a test to help determine if the tmpdoki roms should really be different

 - EEPROM might be wrong, pressing what might be coin3 causes the game to hang
   (see input ports)

 - Video has a 'blitter' but it isn't used by these games, it is used by Rabbit

 - tmpdoki isn't a dual screen game, we should remove the dual screen layout from VIDEO_UPDATE and from the MACHINE_DRIVER, also notice that MAME
   doesn't have a macro for removing previously declared screens.

 - sound (see rabbit.c for preliminary details, not copied here)

 - sprites from one screen are overlapping on the other, probably there's a way to limit them to a single screen

 - priority is wrong.
