Shanghai 3           (c)1993 Sunsoft     (68000     YM2149 OKI6295)
Hebereke no Popoon   (c)1994 Sunsoft     (68000 Z80 YM3438 OKI6295)
Blocken              (c)1994 KID / Visco (68000 Z80 YM3438 OKI6295)

These games use the custom blitter GA9201 KA01-0249 (120pin IC)

driver by Nicola Salmoria

TODO:
all games:
- Blitter needs to be device-ized
shangha3:
- The zoom used for the "100" floating score when you remove tiles is very
  rough.
heberpop:
- Unknown writes to sound ports 40/41
blocken:
- incomplete zoom support, and missing rotation support. Setting the game in
  Game Mode B shows a decent test case for it by starting a play.
- attract mode tries to read at 0x80000-0xfffff area, returning 0 in there
  freezes the demo play for some frames (MT #00985). For now I've returned $ff,
  but needs HW tests to check out what lies in there (maybe a ROM mirror).
- how to play screen is bogus, it basically loses sync pretty soon.

Notes:
- a Blocken PCB shot shows a 48 MHz xtal, game is definitely too slow at
  8 MHz (noticeable thru colour cycling effects)
- Confirmed OSC is 48MHz and OKI resonator is 1.056MHz.
- Hebereke no Popoon has various debug mode switches, the ones found so far:
  $30878e: bit 0 enable, active low.
           If enabled correctly all of the non gameplay screens become
       text stubs;
  $aff14: a non-zero value enables CPU usage in 2p mode.
          As a side-effect this also makes winning condition to never
      satisfy, it goes on indefinitely with the selected characters and
      input methods.
