Summary 05052: dkong dkongo: Switching to TKG-02 (Radarscope Conversion) is no longer creating the proper color palette
Description Starting with MAME 0.147u1 Donkey Kong's color palette is not updating properly when switching Video Hardware --> TKG-04 to TKG-02. A blue 'film' is seen across the screen; palette colors not correct.
Steps To Reproduce -Select dkong ROM.
-Press 'Tab' to bring up internal menu.
-Scroll down to "Driver Configuration" [Newer versions of MAME list this as "Machine Configuration"].
-Press 'Enter'.
-Use arrows keys to switch "Video Hardware" from "TKG-04 (Two board set)" to
"TKG-02 (Radarscope Conversion)".
Additional Information Out of 130,000+ Donkey Kong cabinets sold [ https://en.wikipedia.org/wiki/Arcade_game#cite_note-DonkeyKong-69 ], at best only a couple thousand were Radarscope hardware conversions. A rare version that hopefully can be preserved and represented properly under MAME, once again.

MAME 0.147 also has the proper behavior of the switch in place.
This narrows down the break from between MAME 0.147 on Sept 17, 2012 to MAME 0.147u2 on Oct 30, 2012.

Narrowing it down even further, the breakage is evident under MAME 0.147u1 as well.

MAME 0.147 = September 17, 2012 = Palette switch works fine - TKG-02 Colors correct.
MAME 0.147u1 = October 8, 2012 = Palette switch is broken - TKG-02 Blue film on screen instead.

Here are the list of updates that impacted dkong between MAME 0.147 and MAME 0.147u1:

Monday 17th September, 2012
http://mame.dorando.at/svn/?rev=17962
Memory handler normalization, part 1.
READ/WRITE_DEVICE*_HANDLERs are now passed an
address_space &, and the 8-bit variants get a mem_mask
as well. This means they are now directly compatible
with the member function delegates. Added a generic
address space to the driver_device that can be used
when no specific address space is available. Also
added DECLARE_READ/WRITE_DEVICE*_HANDLER macros to
declare device callbacks with default mem_mask
parameters

http://mame.dorando.at/svn/?rev=17964
Memory handler normalization, part 2. Change legacy
read/write handlers to take an address_space & instead
of an address_space *. Also update pretty much all other
functions to take a reference where appropriate.

http://mame.dorando.at/svn/?rev=17965
Memory handler cleanup 3. Add mem_mask parameter
to 8-bit handlers to match the others. To ease
pain, added DECLARE_READ/WRITE_HANDLER macros that
set up a default parameter. Also updated devcb so
that the handlers can be called with or without the
mem_mask.

http://mame.dorando.at/svn/?rev=17968
Modernized screen update calls (no whatsnew)


Tuesday 18th September, 2012
http://mame.dorando.at/svn/?rev=17987
manual cleanup of mame and mess includes (no whatsnew)

http://mame.dorando.at/svn/?rev=17989
changed most of screen.machine() to machine() (no whatsnew)

http://mame.dorando.at/svn/?rev=17997
INTERRUPT_GEN -> INTERRUPT_GEN_MEMBER (no whatsnew)


Wednesday 19th September, 2012
http://mame.dorando.at/svn/?rev=18012
Removed device_memory_interface from driver_device, fixes issues with dkong clones, and various others, require clean compile (no whatsnew)

http://mame.dorando.at/svn/?rev=18021
dkong fix (no whatsnew)

http://mame.dorando.at/svn/?rev=18028
Since nobody checks for NULLs anyway, make
device_memory_interface::space() assert against NULL and
return a reference, and pushed references throughout all
address space usage in the system. Added a has_space()
method to check for those rare case when it is ambiguous.

Also reinstated the generic space and added fatal error
handlers if anyone tries to actually read/write from it.

Fix for MT5018. [Couriersud]
Also improves blue background levels and gradient for Radar Scope.

The above appears to be the strongest candidate for the regression as there are a couple of references to "DKONG_RADARSCP_CONVERSION".
