- Corrected memory map errors with the SE and Classic
- Preliminary support for the SE's 68000 processor-direct slot
- Preliminary support for the Radius Full Page Display card which goes in the
SE PDS slot
Tilemap system: numerous changes:
* Moved remaining legacy macros and typedefs to tilelgcy.h. This revealed
a few drivers mixing and matching modern & legcy, which have now been
fixed.
* Changed get info callback signature to no longer pass the user_data
pointer, but instead pass a reference to the tilemap object itself.
Updated those few drivers using user_data to pull it out of the
tilemap object with the new user_data() getter method.
* Changed get info and mapping callbacks to be device_delegates so that
they can be described at config time.
* Added tilemap_memory object that is used internally for reading/
writing to memory that backs a tilemap. This object is used to track
a memory pointer that backs tilemap memory, and also is designed to
transparently handle all bus width and endianness associated with
reading and writing data in a tilemap.
* Incorporated two tilemap_memory objects (basemem and extmem) into the
tilemap object and added accessors to them, as well as read/write
handlers for reading/writing to entries stored in the memory. This
means that tilemap get info callbacks can now easily read data out of
the tilemap in a generic way.
* Rejiggered the initialization sequence for tilemap objects so that
the tilemap_manager is not required to be present at instantiation.
* Created a new tilemap_device, which can be used to declare a tilemap
in the machine config, and which also is a tilemap object itself.
The tilemap device will look for shared memory regions called
"<tag>" and "<tag>_ext" and automatically plug them into the tilemap.
The device also provides write handlers that can be used to write
to the tilemap memory and mark tiles dirty, saving the need for each
driver to write their own.
Device system: moved required/optional device finders to a new header
devfind.h.
Atari drivers: removed all playfield and alpha memory and tilemap
variables, apart from those needed by atarivc-using games (this will
become a device in a future update). Updated all Atari 16-bit drivers to
use the new tilemap_device instead, which provides all the needed
functionality in a more generic way.
yes, the filename is a bit ugly, but it's what it represents, I'll see if it can be further split into components later.
all users have been given a brief testing
(for MB-6892). For now these behave the same as bml3 (MB-6890).
Refactor disk controllers and kanji ROM as slot devices. This allows
switching between MP-1802 and MP-1805 disk controllers. MP-1805 disk
controller now works. Kanji ROM now works.
Keyboard scanning in 'counter disabled' mode now works.
imgtool: Add bml3 driver, supporting both single-density (MP-1805
controller) and double-density (MP-1802 controller) disks in D88 format.
mc6843: Work around floppy_get_device() not finding drives attached to a
slot device.Store all 8 bits in CTAR current track register, rather than
excluding bit 7 (needed for bml3 MP-1805 boot)
I have no interest in this *at all* but I keep getting bugged about it so I'm giving people a place to pt notes.
From an objective point of view we at least need somewhere to establish details and proper documentation about the hardware and what the original platform consists of in both terms of PC side, software side and original security side before the there is no hope at all due to the travesty being created by all the hacked to run on PC dumps or 'files copied from mounted encrypted partitions' type junk. That at least I feel is our duty because nobody else is going to care.
