1. Renamed MACHINE_DRIVER_* to MACHINE_CONFIG_* to match the name
of the object it actually describes. The MDRV_* prefix may
eventually be bulk updated at some point, but not now.
2. MACHINE_CONFIG_START() now takes a driver_data_t-derived
class as a required second parameter. This means that
MDRV_DRIVER_DATA() is no longer required, and every "root"
machine config *must* specify a driver data class (or driver_data_t
itself if the driver has not yet been updated to use driver data).
3. New MACHINE_CONFIG_DERIVED() macro defines a machine_config
that is derived from another machine_config. This takes the place
of the very typical MACHINE_DRIVER_START()/MDRV_IMPORT_FROM()
combination.
4. New MACHINE_CONFIG_FRAGMENT() macro defines a partial
machine_config that can only be included in another "root"
machine_config. This is also used for machine_configs that are
specified as part of a device.
5. Changed MDRV_IMPORT_FROM() to MDRV_FRAGMENT_ADD() to more
accurately describe what is happening.
6. Added asserts to the above three macros to ensure they are
properly used.
Updated all machine drivers to use the new macros. Search & replace
lists below cover 99% of the changes, with just a few manual fixups.

Final step: run mame -valid and fix the incorrect macros at the lines
where the asserts show up.
split screen and scrolling effects using a regular mc6845. [Wilbert Pol]
Interface change:
The screen tag is no longer mandatory. If a screen tag is provided then the mc6845 device will resize
the screen and visible area based on the parameters set in the 6845 config and registers. If the screen
tag is not provided then the driver is supposed to be in charge of setting the proper screen configuration.
Warning: This breaks the relationship between the timing of a screen device and the signals generated
by the 6845.
it's related to:
00171: lethalen: mask rom check they all come up bad.
in konicdev.c there's in READ8_DEVICE_HANDLER( k053244_r ):
addr = (k053244->rombank << 19) | ((k053244->regs[11] & 0x7) << 18) | (k053244->regs[8] << 10) | (k053244->regs[9] << 2) | ((offset & 3) ^ 1 );
for the A10 test and A8 test (GFX2 region of lethalen) we need:
........ | ((offset & 3) ^ 3 );
is there any doc about k053244?
Chihiro.c Improvements: [Samuele Zannoli]
- Fixed the mapping of the bios at the top of the cpu addrsss space
- Updated the ram size to 128 megabytes
- Added some SMBus handling, to let the bios run
- Added placeholders for a few devices on the PCI bus
- Added the "jamdis StartAddress,Length" command to the debugger that lets you disassemble the "jam table" instructions used by the bios to do some basic hardware initialization.
This time it works for good ;)
