Double Dragon     (c) 1987 Technos Japan
Double Dragon II  (c) 1988 Technos Japan

Driver by Carlos A. Lozano, Rob Rosenbrock, Phil Stroffolino, Ernesto Corvi
Toffy / Super Toffy added by David Haywood
Thanks to Bryan McPhail for spotting the Toffy program rom encryption
Toffy / Super Toffy sound hooked up by R. Belmont.

BM, 8/1/2006:

Double Dragon has a crash which sometimes occurs at the very end of the game
(right before the final animation sequence).  It occurs because of a jump look up
table:

    BAD3: LDY   #$BADD
    BAD7: JSR   [A,Y]

At the point of the crash A is 0x3e which causes a jump to 0x3401 (background tile
ram) which obviously doesn't contain proper code and causes a crash.  The jump
table has 32 entries, and only the last contains an invalid jump vector.  A is set
to 0x3e as a result of code at 0x625f - it reads from the shared spriteram (0x2049
in main cpu memory space), copies the value to 0x523 (main ram) where it is later
fetched and shifted to make 0x3e.

So..  it's not clear where the error is - the 0x1f value is actually written to
shared RAM by the main CPU - perhaps the MCU should modify it before the main CPU
reads it back?  Perhaps 0x1f should never be written at all?  If you want to trace
this further please submit a proper fix!  In the meantime I have patched the error
by making sure the invalid jump is never taken - this fixes the crash (see
ddragon_spriteram_r).



Modifications by Bryan McPhail, June-November 2003:

Correct video & interrupt timing derived from Xain schematics and confirmed on real DD board.
Corrected interrupt handling, epecially to MCU (but one semi-hack remains).
TStrike now boots but sprites don't appear (I had them working at one point, can't remember what broke them again).
Dangerous Dungeons fixed.
World version of Double Dragon added (actually same roms as the bootleg, but confirmed from real board)
Removed stereo audio flag (still on Toffy - does it have it?)

todo:

banking in Toffy / Super toffy

-- Read Me --

Super Toffy - Unico 1994

Main cpu:   MC6809EP
Sound cpu:  MC6809P
Sound:      YM2151
Clocks:     12 MHz, 3.579MHz

Graphics custom: MDE-2001

Does this make Super Toffy the sequel to a rip-off / bootleg of a
conversion kit which could be applied to a bootleg double dragon :-p?
