scsi: sync rest of lines with input buffer (nw)
---
The 9801f will read the hdd but appears to not like disks without 256 byte sectors.
The ux and rs don't even attempt to access the sasi controller and seem to have no driver in their firmwares, are they supposed to have an external rom?
a general workbench list and an application list for testing. Images in
those lists are either verified good or best available currently. Many
images are still missing.
Explicit regions in address maps (AM_REGION) are now looked up relative to the
device rather than as siblings when in an internal address map (similar to
devices and shared pointers) Besides being more orthogonal than before, this
allows internal ROMs of MCUs and similar devices to be hooked up in a nicer
and more foolproof way. Updated the m37710 and m5074x (m6502 derivative)
to take advantage of this.
Divided the M37702/M37710 into specific models, with each model having its own
internal address map containing the correct amounts of internal RAM and ROM.
M37702 MCUs found on various Namco PCBs are now all unique devices and have
their respective internal ROMs loaded as device ROMs.

Also did some spring (fall) cleaning in addrmap.c/memory.c/dimemory.c
m_devbase (the base device used for tagmap lookup when late-binding handlers and
finding memory regions and shares) is now a reference rather than a pointer,
since we know what it is when the address_map_entry is constructed and it
doesn't change (it depends solely on whether it's an entry in an MCFG-provided
address map or an internal one) And for the same reason, there's now only one
m_devbase per address_map_entry rather than individual copies for
read/write/setoffset/sharedptr.
Removed mysterious unused address_map_entry member "m_region_string", along
with a silly assert probably left over from when Aaron was replacing AM_BASE
with AM_SHARE years ago.
Added a comment noting that "make sure all devices exist" in
device_memory_interface::interface_validity_check() actually does nothing,
like the proverbial goggles. The reason there's just a comment and not a fix
is I haven't figured out how to fix it yet
(is it possible to extract the original device tag that was given to a
proto-delegate? Sorry, the template hell in devdelegate.h and
lib/util/delegate.h makes me want to run screaming like a little girl)
basic allocation and access handlers, and converted a few
drivers to use this instead of code from cartslot.c [Fabio Priuli]
out of whatsnew: the RAM socket part is just a proof of concept,
and the natural extension of the line of thought which lead me
to this generic socket/cartslot. it might allow to convert current RAM
device to be a slot device as well (after some refactorization, of
course, since current code lacks many of the necessary features),
or be removed soonish, depending on consensus.
moved some of the Raiden 2 cop emulation to a new device (just the memory DMA stuff, including private buffer copy code) and started sharing it with legionna.c in order to avoid code duplication. We can slowly move other duplicate code over too and eventually kill the old seicop.c
- Rewritten cart emulation to use slot devices (many
"mappers" do not fully work) and unified cart handling
among 8bit home computers, XEGS and Atari 5200
- Added support for loading carts with bankswitch to all XL/XE
models
- Added support for loading XEGS carts in Atari 8bits home
computers (XEGS instead will only load XEGS games until
support for the keyboard add-on is included)
- Big clean up of the driver, simplifying memory map, removing
writes to ROM, etc.
- Changed NOT_WORKING flag to IMPERFECT_GRAPHICS
in 600XL, 65XE, 800XE and XEGS since they should now be
working to the same extent of the 800XL, and bugs shall be
reported.
as a consequence of the above changes, the new softlists a800.xml, a5200.xml
and xegs.xml are not compatible anymore with 0.154: keep the old xmls until
0.155 if you don't compile your own exe
- Rewritten cart emulation to use slot devices
- Removed POKEY chip from the main unit since it was inside
the carts (of course it gets enabled when you launch a game
who contained it in its cart)
- Added support for the High Score cart as a passthru cart: when
you mount hiscore, a -cart2 switch will become available to mount
the game you want to play
- Properly implemented XBoarD and XM expansions as
passthru carts as well, so that new syntax to run dkxm.a78 is
"mess a7800 -cart xm -cart2 path\to\games\dkxm.a78"
High Score support for XM shall work as well.
- Big clean up of the driver, simplifying memory map, removing
writes to ROM, etc.
Out of whatsnew: In conclusion, a7800.c has been brought into the new millennium ;-)
the implementation and removed Supercharger tapes from the main system.
The -cass media switch (to load the tape file) will become available only
when you mount the Supercharger cart. [Fabio Priuli]
and hooked it up to the namcos1, namconb1 and namcofl drivers [Alex Jackson]
digfx.c: Make some members protected instead of private to be less fascistic
and more consistent with other device_interfaces.
- Added additional ROMs for TK3000
- Added preliminary mono/color config switch for pre-IIgs machines (doesn't yet work in lo-res)
- Moved Laser 3000 to its own driver since it's not very Apple-like and got it to boot into BASIC.
