* Cleaned-up the irq / nmi firing and fixed irq acks;
* Cleaned-up the memory map;
* Added coin counter, coin lockouts and added a second coin chute;
* Documented some unclear i/os;
* Flagged the game as GAME_IMPERFECT_SOUND since it uses samples instead of proper discrete sound emulation;
argus: fixed service switch (was defined to port that does not exist), and fixed DIPLOCATION order.
valtric: fixed note for how to enter test mode.
coin1 and coin2 were swapped, and fixed DIPLOCATION order.
butasan: coin1 and coin2 were swapped, and fixed DIPLOCATION order.
To enter test mode:
argus: power ON while coin2 is ON
valtric: power ON while coin1 is ON
butasan: power ON while service SW is ON
I don't know how to map multiple MAME keys to 1 real port on PCB, so I mapped service switch of butasan to "TEST(F2)".
As a result of this, you have to press F2 twice to use as normal service switch.
- DMA protection emulation for qmegamis, fixes in-game graphics [Deunan Knute]
- Correct decryption key for Extreme Hunting [CaH4e3]
Sega scholars will find the decrypted protection data for qmegamis hilarious.
Bonus points if the game actually does a strcmp() on it.
(Protection data is uploaded to roms/unemulated/Sega/Naomi/qmegamis_prot.zip).

Hello again,
Attached is a diff for 0132u5 cischeat driver that mainly fixes a rather
stupid bug: "break;" was omitted in a switch/case, causing severe glitches
in Scud Hammer (no mametesters bug id) and Arm Champs II (bug id 03191).

Subject: namcos2 bubbletr crosshair
Hi,
Attached is a diff for 0132u5 that adds a gun crosshair to namcos2
bubbletr (Bubble Trouble), it's required to be able to calibrate
the gun correctly.
If you don't mind, I've also removed the 'game not working flag', as
IMO the game is playable just fine.
Greets,

Subject: namcos22 timecris crosshair fix
Hello,
Attached is a diff for 0132u5 that fixes a problem with the Time Crisis gun crosshair.
The right and bottom parts of the screen couldn't be accessed, and you couldn't shoot
off-screen. Off-screen shooting has a function in test mode, in the fix this is the
bottom edge of the screen. This fix requires the user to (re)calibrate the gun via
test mode.
Greets,

Subject: [Fwd: small fix in patch file, final one] (Gnet update/fix to reset mechanism, tested on real hw)
The problem in the old patch was that after g-net makes a card reset,
intentionally the lock mechanism should be reenabled. I did not
implement it because
The old MAME implementation had a wrong card reset:
Bios makes an unlock and then a card reset, this was wrong because card
reset was mapped wrong
In the right way card reset is done via the PCMCIA controller, after
this card reset G-NET again has to make a UNLOCK
Applied the latest patch, PLEASE DO NOT SUBMIT OR USE THE OLD ONE
MB3773 driver is included
Best regards

* DIP Switches.
* Simulated spark-watchdog circuitery.
* Demuxed custom port.
* NVRAM support.
* CPU clock derived from #defined crystal.

* Coin related counters.

The 4 games are fully playable. Sound seems to be discrete, so the circuitery need to be traced.
Colors are still wrong.

Multi-Poker [Roberto Fresca]
- Implemented cartridge protection chip mechanism
- Added protection data for doa2 and doa2m
- Added real dumped cartridge X76F100 data for doa2/doa2m
doa2 now hangs in a loop at c001192 waiting for some interrupt(?) that
never occurs. doa2m is similar. Kale, would you mind having a look?
Encryption fairies may wish to look and see if the protection data is derived
from the ROM contents at all, although it appears there's maybe just a ROM
inside the protection ASIC.
