0.88u2

 

General Improvements

--------------------

 

Further improvements to the FD1094 decryption, this is now almost fully understood,

additional FD1094 cpus are needed to work out the remaining details.  Keys are now

stored in the romsets as they should be a close representation of the data stored in

the FD1094 CPUs [Nicola Salmoria]

 

Fixed a few things which missed the Namco update in u1 [Phil Stroffolino]

 

Corrected some rom names in Crowns Golf [shinobiZ]

 

Corrected some rom names in Pengo [Gerald]

 

Improvements in Mighty Warriors Driver [Pierpaolo Prazzoli]

Added sprites buffer which fixed the "invisible" sprites

Fixed text tilemap scrollx offset

Haze added palette brightness

 

Improvements to Twin Brats [Pierpaolo Prazzoli]

Fixed sound banking

Changed service switch button

Changed visible area

Merged memory map

 

Moved gamename prefixes to end in pc10, nss and megatech [Aaron Giles]

 

Fixed Joystick Axis problem [Aaron Giles]

 

Discrete Sound Improvements [Derrick Renaud]

 

Discrete Sound Changes

======================

* DISCRETE_555_ASTABLE - added option to use quick charge diode (will be

needed for frogs.)  Added option to disable oscillation if R1 (charge) is out

of circuit (will be needed by invaders.)

* DISCRETE_555_CC - modified to discharge cap due to natural losses if there

is no charging current (needed by frogs.)  This makes it more accurate then

the current perfect cap that will retain a charge forever.

* modified all current drivers to use new code.

 

New Discrete Modules Added

==========================

* DISCRETE_555_MSTABLE - 555 Monostable simulation

 

Game Driver Changes

===================

* frogs - added sound hooks.  Added discrete "tongue" sound effect.

 

Fixed bug in discrete code [brad Oliver]

 

Improvements to Astrocade driver [Frank Palazzolo]

- Professor Pacman Driver - works but fails 2 self-tests yet

- Fixed collision detection in all games

- Added NVRAM handling to robby (and profpac) - still not working

always but self-tests pass.

- Fixed bugs in astrocade sound code

- Switched astrocade sound to stream system

- Support stereo in wow, robby, gorf, profpac (Sounds great now!!)

- Leds and coin counters added

- All activecpu_get_reg() calls from astrocde games have been

  replaced with proper 16-bit Z80 port support through memory system

- Renamed sndhrdw/astrocde.c to sndhrdw/wow.c since it is game-

specific

 

Fixed NMI handling in NEC cores [bryan McPhail]

 

Cleaned up Twins driver and changed to use V20 [Pierpaolo Prazzoli]
