0.77

General Source Changes
----------------------

Fix to allow a driver to have MSM6295s and plain ADPCM voices coexist
(required for gcpinbal). [R.Belmont]
src/sound/adpcm.c

Full Sound / Music in Grand Cross [R.Belmont]
src/drivers/gcpinbal.c


Improved Bishi Bashi colours [Angelo Salese]
src/drivers/bishi.c
src/palette.c
src/palette.h

Fixed ckongs sprites [Pierpaolo Prazzoli]

Updated Double Dragon Driver [Bryan McPhail]
- 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?)

src/drivers/ddragon.c

Various ST-V improvements [Angelo Salese]
src/drivers/stv.c

Twin16/TMNT fixes [Curt Coder]
drivers/twin16.c

- Fixed cuebrick NVRAM handler
- Added watchdog reset

drivers/tmnt.c

- Fixed mia/mia2 inputs/dips
- Fixed visible area in cuebrckj/mia/mia2
- Changed cuebrckj to "Cue Brick (World version D)", since text
is in English)

TMS32031 Fixes [Aaron Giles]
many fixes to the TMS32031 core; Offroad Challenge is almost playable as a
result, minus the fact that the clipping plane seems to like clipping out
the cars during the race. But the terrain problems are fixed at least.

Memory Annoyance Fix [Aaron Giles]
Unmapped memory accesses always reported the raw byte address, not the
CPU-level address. This is annoying for chips like the TMS34010 or the
TMS32031, so now the effecitve offset is logged instead, taking into account
the address shift.

Some Input Port Corrections [Robin Merrill, fixed by Bryan McPhail]

OSD Fix [Aaron Giles]
This is a minor fix to enable the OSD for non-debug builds regardless of
the -debug flag

Misc Fixes [Nathan Woods]
src/usrintrf.c:
- Adds a handful of comments to uifontdata[]
- Changes character 14 to a solid circle; previously this
character was blank and unused
- Miscellaneous changes within #ifdef MESS

E' uscita anche la 077u1, ma sembra si tratti solo di una release interna per poter testare al meglio il nuovo gestore di CHD ed evitare che milioni di fan del MAME si ritrovino con GIGA di roba da riscaricare!!!!


La prossima release pubblica dovrebbe essere la 077u2.....


Attendiamo fiduciosi!
