Also note that there is no analog sound. Apparently the sound is similar to the regular Space Invaders sounds. The Guru has the board out and hooked up if anyone wants to take a stab at getting the sounds going in this game.
Back to fixing some bugs...
Quite possibly the most useless RSP change I'll ever make, given that no game should ever be affected by these changes. But, eh, accuracy. Apparently only the accumulator registers are initialized to a non-random value on power-on, and apparently the RSP executes exactly one instruction before kicking over into single-step mode when it's set in the status register.
- Fixed accumulator state on powerup by testing against real hardware
- Fixed single-step behavior by testing against real hardware
Added new clone "Player's Edge Plus (XMP00006) Multi-Poker"
Increased DUART memory size
Minor white space clean up & commented the rom defs with game names.
The system 10 & 12 clock speeds have been raised as they run on an upgraded chipset.
All clocks are currently set to divide by 2 externally, I don't know if this is correct.
The clock is also divided internally as we have no wait states, incorrect dma timing, no gpu timing, no dma bus stealing and no gte timing.

Credit should go to Robbert.
"frogger.c, amidar.c, scramble.camidar.c, frogger.c (all sets),
galaxian.c (froggs at least), scramble.c (scramble+many sets): When it is player
2's turn and the screen is flipped it is offset so that the scores sit in
the middle of the screen."

Subject: Fixed DBREED72 crash in 0.122u5
Hello. This patch fixes the crash of DBREED72 in m72.c driver caused by
two lines mistakenly removed during the last 0.122u5 update.
Subject: [patch] Fix megaplay.c0122u4red
This fixes the crash reported as megaplay.c0122u4red. The driver
doesn't map the offset into the correct range for the handler. -bios 1
still shows corrupt graphics, but at least it doesn't crash anymore.

Subject: fix for lcasino0111ora.diff
"ltcasino.c I believe there was no Little Casino 2, but only Little
Casino. Digital Controls re-used Little Casino title even though later versions
of Little Casino might have appeared differently.
It should be Little Casino (older) and Little Casino (newer) to reflect
game differences with Little Casino (older) being an older version clone of
Little Casino (newer) which would be latest revision."
Changed name to Little Casino (older) and Little Casino (newer), also
renamed set ltcasin2 to ltcasinn.
Verified and changed cpu frequencies and oki m6295 pin 7 on the
following pcbs:
Asuka&Asuka, Cadash, Equites h/w games and sound board, F1GP, Super
Formula, Gladiator, Ping Pong king, Great Swordsman, Irem m52 sound
board, Tropical Angel, Explosive Breakers, Magical Crystal, Mad Gear,
Roller Aces, Chinese Hero, Simpsons, Golfing Greats, Time Pilot 84.
Updated Xtal.h to use new OSC values found on Great swordman, Gladiator
h/w and Equites sound board.
Updated informations in Equites.c for the sound board
- Removed videoram_w, colorram_w and spriteram_w and changed all drivers using it to access RAM directly. Still kept the _r function as some old style drivers are relying on them for mirroring support. Will investigate and address those next
