- Added irqs ack
- Implemented raster irq
- Fixed coin2 and service input not working during the game
- Added watchdog
- Fixed visible area
- Added video enable and irqs enable flags
renamed ikaria to ikarinc (for Ikari No Continues)
ikari is the JAMMA board, with conitnues
ikaria is the non-JAMMA board, with continues
ikarinc is the non-JAMMA board, without continues
New clones added

Ikari Warriors (US) [Nicola Salmoria]
Since I touch up a couple of things and test each driver after the automated merge, it still takes a few minutes for each file. More IO_MAP merges will trickle in over the next few days.
It's likely not worth writing every driver in the whatsnew.txt, since there will be ~100.
- Added Magic Joker.
- Fixed the 3rd background offset to Galaxi.
- Remapped inputs to match the standard poker games.
New games added or promoted from NOT_WORKING status

Magic Joker (v1.25.10.2000) [Roberto Fresca]
* Adds MCS48_INTERNAL_ROMBANK define to header
* Drivers which need to control the ea line have to initialize banking for internal/external rom
This is not yet optimal but works as expected with existing drivers and modified mario.c
(not worth putting in whatsnew)
Please note, this does touch mario.c and dkong.c (two drivers which are currently undergoing modifications), but it does so unobtrusively. I also asked the proper parties before committing.
All games are tested and working after this patch.
* MB8884 is a I8035 ==> 12 addr, no internal rom map
* EA line high: external access - this is "default"
The whole EA implementation is as Aaron named it, cheeky. EA=1 external rom access, EA=0 internal rom access.
But all variants are treated the same, i.e. for i8035, MB8884, I8039, the external rom is used in the same
way as the internal.
These ports are actually ports which sink current on logical 0. With a logical 1, they are in high impedance mode and may be read. The high impedance is treated as logical 1 by TTL gates connected to them.
Fixed bug in my recent DISCRETE_MIXER update.
Note: the DISCRETE_MIXER bug caused most of the speed increase of its optimization and caused some games to crash. Donkey Kong is now at 14% faster on my machine then when I started. Better then nothing.
For those keeping score dkong was at 268% on my computer before I started optimizing. It now runs at 342%. The 555 and mixer changes also speed up just about every current discrete game.
