Super Shanghai Dragon's Eye (c) 1992 Hot-B
PCB is manufactured by either Hot-B or Taito, but uses Data East custom
chips.
Emulation by Bryan McPhail, mish@tendril.co.uk
+ Charles MacDonald, David Haywood
----
Stephh's notes (based on the games M68000 code and some tests) :
0) all games
- There is no confirmation yet that the "Demo Sounds" Dip Switch does
something as I don't see where bit 0 of 0xfec04a is tested 8(
- The First "Unused" Dip Switch is probably used in other (older ?) versions
to act as a "Debug Mode" Dip Switch. When it's ON, you have these features :
* there is an extended "test mode" that also allows you to test the
BG and Object ROMS via a menu.
* You can end a level by pressing BUTTON3 from player 2 8)
- The "Adult Mode" Dip Switch determines if "Shanghai Paradise" is available.
- The "Quest Mode" Dip Switch determines if "Shanghai Quest" is available.
- The "Use Mahjong Tiles" Dip Switch only has an effect when playing
"Shanghai Advanced".
